What Are Skateboard Ramps Made of: Materials Compared

Skateboard ramps are made from a core riding surface, a structural frame, and a substrate for support. The riding surface is typically birch plywood, a paper-based composite like Skatelite or Pro Skate Composite, waterproof laminated plywood (SkatePly/HDO), aluminum sheet, or concrete. The frame is built from lumber (2x4s) or aluminum tubing, and the substrate is often marine-grade or exterior-grade plywood.

That list covers the basics, but the real choice isn’t about naming materials. It’s about matching a material’s performance, its grip, speed, durability, and maintenance, to where the ramp lives and who rides it. A birch plywood surface is a dream indoors but a full-time job outdoors. A steel plate might stop a fire but will send a skater sliding. When choosing, a key question is: what are skateboard ramps made of? (See our guide to the best skate ramps for examples.)

What follows is a breakdown of every major material to answer the what are skateboard ramps made of question, grounded in manufacturer specs and a decade of watching what lasts and what fails. We’ll look at the specs that matter, the common DIY mistakes that cost you a season, and the one rule that reframes the entire indoor versus outdoor decision.

Key Takeaways

• Birch plywood is the user-preferred surface for its consistent grip and feel, but outdoors it needs constant scheduled maintenance as it can delaminate.
• For permanent outdoor parks, composite panels (Skatelite, Pro Skate) or aluminum are the default choice; they resist water, require virtually no maintenance, and meet public safety standards like ASTM F2334.
• Never use standard “exterior-grade” plywood as a riding surface; it’s for vertical walls, not horizontal decks, and delaminates in a matter of weeks outdoors even with sealant.
• The substrate under a composite surface must be at least 12mm thick (marine-grade plywood is recommended by Surface Matter) and can be protected with tar paper, but KO Ramps states that covering outdoor plywood ramps with tarps is ineffective long-term.
• Aluminum ramps (like RedRailed) use specific alloys (5052 H32 for surfacing, 6061-T6 for frames) for corrosion resistance and strength, making them suited for harsh climates.

The Core Materials: From Wood to Composites

To understand what skateboard ramps are made of, we’ll look at each layer. A ramp isn’t one thing; it’s a stack. The riding surface is what your wheels touch. Under that sits a substrate for stiffness, and under that is the structural frame. Choosing wrong at any layer means a ramp that feels dead, wears out fast, or just falls apart.

ASTM F2334-18 establishes the safety, performance, and maintenance requirements for above-ground public-use skatepark facilities, including guardrails, riding surfaces, and copings. This standard guide is the benchmark for commercial ramp construction.

Birch Plywood: The Gold Standard (With a Catch)

Ask any seasoned rider what they want under their wheels, and birch plywood wins almost every time, similar to the high-quality wood used in skateboard deck materials. It’s consistent, relatively fast, and forgiving when you crash. The Middlezoy Parish Council report, which includes direct manufacturer correspondence, notes birch plywood is “almost overwhelmingly users’ first choice for a riding surface.”

But there’s a massive caveat that DIY builders miss. Outdoors, birch plywood needs “constant ongoing maintenance and scheduled replacement.” That’s not a suggestion; it’s a forecast. KO Ramps states that even “exterior grade” plywood, the stuff sold for outdoor decks, is not intended for horizontal applications exposed to weather. They report it “can start to delaminate in a matter of weeks or months.”

The fix isn’t a tarp. KO Ramps says covering outdoor plywood ramps with tarps is ineffective long-term because “water will always find its way in, resulting the plywood to warp and delaminate.” If you must use wood outdoors, you need a plywood specifically engineered for the job, like SkatePly. This material has a birch plywood core but is laminated on both sides with a HDO (High Density Overlay) phenolic overlay and glued with exterior phenolic glue to prevent delamination.

Composite Panels: The Professional’s Choice

When you see a smooth, often colorful surface at a public skatepark, you’re likely looking at a composite panel. Brands like Skatelite, Ramp Armour, and Pro Skate Composite dominate this category. They’re ranked as the second preferred riding surface after birch plywood in the Middlezoy report.

These aren’t just fancy plastics. Pro Skate Composite, for example, is made of celluloid fibres impregnated with phenolic resins. The result is a surface that absorbs no water, is impact-resistant, and provides consistent grip. Rhino Ramps uses a similar composite they describe as fire-resistant, with a glassfibre reinforced PP-underlay to reduce noise, they claim a decibel rating below average office noise (50 db).

The installation is specific. Surface Matter, a distributor of Skatelite, mandates a minimum 12mm substrate (they recommend marine-grade plywood) and advises fastening sheets every 200mm with a 3mm expansion gap between panels. This precision is why composites are rarely a DIY-first material; they’re installed by pros who follow the manufacturer’s guide to the letter.

Aluminum: The All-Weather Contender

For a completely different approach, look to companies like RedRailed. Their ramps are all-aluminum, using Aluminum 5052 H32 for the 3/16” thick surfacing and skirting, and Aluminum 6061-T6 for the frame. The surfacing is welded to the frame from underneath, leaving no bolts to back out. This makes them “virtually maintenance free” and suited for harsh climates, as the aluminum’s oxide film reforms to protect against corrosion.

Concrete and Steel: The Niche Players

Concrete is the third preferred surface in the Middlezoy ranking. It’s permanent, creative for bowls, but impossible to alter once poured. Steel plate may be considered where fire risk is the main concern, but it is now the “least preferred riding surface.” The report states most reputable suppliers discourage it because it’s slippery, and repairs via welding are problematic, a welded repair on a steel ramp may have a “future lifespan of only 1-2 years” due to distortion from temperature changes.

Material	Best For	Key Limitation	Maintenance Level
Birch Plywood	Indoor ramps, temporary outdoor setups	Delaminates quickly outdoors without rigorous upkeep	High (constant sealing, scheduled replacement)
Composites (Skatelite/Pro Skate)	Permanent outdoor parks, public facilities	High cost, professional installation recommended	Very Low (virtually none)
Aluminum (RedRailed)	Outdoor parks in harsh climates, portable setups	Can be expensive, different riding feel than wood	Very Low
Concrete	Permanent bowls, large-scale parks	Zero flexibility after pour, requires skilled construction	Low
Steel Plate	Specific fire-risk scenarios (largely historical)	Very slippery, poor repairability	Medium

Indoor vs. Outdoor: The Material Stacks Change

The biggest mistake I’ve seen a hundred times is using an indoor material stack outdoors. The physics don’t care about your budget. Water, UV, and temperature swings will dismantle a ramp built with the wrong assumptions.

The Outdoor Imperative: Waterproof Everything

For any ramp exposed to weather, a waterproof riding surface like composites or aluminum is most durable. Sources disagree on birch plywood: Radiiramps notes it is users’ first choice but requires constant maintenance outdoors, while KO Ramps warns standard ‘exterior grade’ plywood delaminates quickly and recommends products like SkatePly or birch plywood glued with exterior phenolic glue.

The substrate also needs protection. While Surface Matter recommends installing tar paper under Skatelite to protect the plywood substrate, that’s a professional tactic for a system designed to get wet. Tarping a finished plywood ramp, as KO Ramps warns, is a losing battle because water penetrates screw holes and joints.

The Indoor Simplicity: Wood is King

Inside a warehouse or garage, you can use the classic, beloved stack: a birch plywood riding surface on a standard plywood substrate, framed with 2×4 lumber. The lack of moisture means the wood stays stable, the grip remains consistent, and the only maintenance might be occasional resurfacing from wear. This is where DIY shines, the materials are available at any hardware store, and the techniques are well-documented.

Common mistake: Using “exterior-grade” plywood from a big-box store as your riding surface. It’s meant for shed walls, not skate decks. That thin top layer will peel up within a season, leaving a hairy, splintered mess that ruins wheels and skin.

Here’s the material stack for each scenario:

Outdoor Park Stack:

1. Riding Surface: Skatelite Pro Composite Panel
2. Substrate: 12mm Marine Grade Plywood (with optional tar paper underlay)
3. Frame: Pressure-Treated Lumber or Aluminum Tubing
4. Fasteners: Exterior-Grade Screws, pre-drilled and countersunk

Indoor DIY Stack:

1. Riding Surface: 6.5mm Birch Plywood (RIGAHEKSA or equivalent)
2. Substrate: 12mm RIGAPLY WG/WG or Standard Plywood
3. Frame: Standard 2×4 Lumber
4. Fasteners: Drywall or Deck Screws

Navigating the Plywood Maze: Grades, Glues, and Guarantees

When the research says “marine plywood” and another source warns against it, you’ve hit the core confusion in ramp building. Here is the clarification.

Marine Plywood (BS1088): A Substrate, Not a Surface

Surface Matter recommends marine grade plywood as the substrate under Skatelite. As a stiff, stable base that handles moisture better than standard plywood, it’s recommended for the layer under the composite. However, KO Ramps warns that marine plywood has a thin top layer that can peel off and get hairy when used as the skate surface. So its role is structural support, not the riding layer.

The “Exterior Grade” Trap

This is the plywood that ends most DIY outdoor projects prematurely. KO Ramps is blunt: it’s “not intended to be used for horizontal applications such as decks and floors that are exposed to weather.” The veneers are inconsistent, the glue isn’t always waterproof, and it delaminates in a matter of weeks or months. Buying it because it’s cheaper than birch is a false economy.

What About All Those Other Plywoods?

Manufacturer specs point to very specific products. These are industry-grade materials with known performance. For a home builder, the lesson is to look for void-free, high-density plywood with a phenolic resin glue if it’s going anywhere near moisture.

Sourcing and Installation: Where the Specs Get Real

You can know every material code, but if you don’t know how to get it or put it together, the ramp doesn’t get built. This is where pro knowledge saves months of frustration.

Where to Buy Premium Surfaces

You don’t buy Skatelite at a lumberyard. Skatelite and Ramp Armour are distributed through specialty skatepark construction companies and authorized dealers like Surface Matter. Pro Skate Composite is sold through manufacturers like KO Ramps. For the DIYer wanting a composite feel, SkatePly is a more accessible, waterproof plywood alternative often sold by the same suppliers. Aluminum systems like RedRailed are sold as complete, pre-assembled units.

The Non-Negotiable Installation Rules

Ignoring these turns premium materials into expensive failures.

• Pre-drill and countersink. Surface Matter advises pre-drilling and countersinking (6mm) all screw holes in Skatelite to prevent “biting” and damaging the sheet.
• Fastening pattern is critical. Fasten every 200mm in the field and along the perimeter. On a transition, follow a staggered pattern (up three holes, fill two) to distribute tension.
• Frame attachment is mandatory. Every fastener must anchor into the structural frame, not just the substrate. A screw holding just plywood will pull out under impact.
• Allow for expansion. That 3mm space between sheets isn’t a suggestion. Without it, sheets buckle in the heat.

Where this goes sideways: Stapling a composite sheet directly to the frame without the proper substrate. The panel needs the plywood underneath to distribute impact forces. Without it, the composite can crack under a heavy landing, voiding the warranty and creating a sharp hazard.

Common DIY Mistakes and How to Avoid Them

Trust the process, not just the trick. Building a ramp is a test of patience and precision. These are the errors that send people back to the hardware store.

1. Choosing Plywood by Price, Not Spec. Buying the cheapest “BCX” plywood because it looks smooth. The core is full of voids, it will sag between supports, and the glue isn’t waterproof. Fix: Spend the extra on void-free, exterior phenolic glue birch or dedicated skate plywood like SkatePly.
2. Skimping on Fasteners. Using drywall screws outdoors or under-driving screws to save time. Drywall screws corrode and snap. Under-driven screws create a lip that catches wheels. Fix: Use exterior-grade deck screws or structural screws and drive them flush or slightly countersunk.
3. Ignoring Transition Support. The curve of a ramp focuses force. Using the same support spacing on the transition as on the flat deck. Fix: Double the support framing under the transition. Many plans call for increased support framing under the transition.
4. Forgetting About Coping. The metal pipe at the top of a ramp (coping) is what you grind. Using thin-walled electrical conduit because it’s cheap. It dents instantly and becomes dangerous. Fix: Use robust steel pipe or, for aluminum ramps like RedRailed, the specified 2” diameter aluminum tubing.

DIY Ramp Construction Steps and Materials List

Building your own ramp starts with a solid plan. The core structure is a frame, typically built from lumber or metal tubing, which defines the ramp’s shape and strength. Over this frame, you install a stiff substrate, like plywood, to create a smooth curve. The final and most critical layer is the riding surface. For outdoor builds, standard birch plywood is a popular user choice but requires constant ongoing maintenance and scheduled replacement outdoors. Composite panels or specialized laminated plywoods are designed to withstand weather with less maintenance. Avoid materials like fibreglass, which has been historically rejected, and mild steel plate, which is the least preferred riding surface.

Foundation and Ground Preparation

A stable base is essential. The ground under your ramp must be level and compact to prevent shifting and settling that warps the structure. For permanent outdoor installations, a concrete pad is the gold standard, providing a flat, durable foundation that resists frost heave and water damage. If you’re building on soil or grass, use rot-resistant lumber for any ground-contact framing. Ensure proper drainage away from the site; pooling water will undermine the foundation and accelerate rot in wooden components. A well-prepared base is the first defense against a wobbly, unsafe, or short-lived ramp.

Tools Needed for Building a Skateboard Ramp

You’ll need standard carpentry tools for a wooden ramp build. A circular saw or jigsaw is essential for cutting sheet materials like plywood for the substrate and surface. A power drill with driver bits is necessary for assembling the frame and attaching the riding surface. If your design uses specific fastening patterns, like screws spaced evenly across a composite panel, a tape measure and marking tool are crucial. For repairing steel ramps, welding is the least preferred method due to distortion. A level is indispensable for ensuring your frame and foundation are perfectly flat before adding any riding surface.

Frequently Asked Questions

What is the best material for a skateboard ramp?

For indoor use, birch plywood is a user-preferred surface for its performance and feel. For permanent outdoor installations, composite panels like Skatelite or Pro Skate Composite are the best due to their weather resistance and near-zero maintenance. Aluminum systems like RedRailed are also excellent for outdoor durability.

Can I make a DIY ramp for skateboarding?

Absolutely. For an indoor ramp, you can successfully build with birch plywood, standard lumber, and basic tools. For an outdoor DIY ramp, your choice is critical: you must use a waterproof riding surface like SkatePly or commit to a rigorous sealing and maintenance schedule for birch plywood. Avoid standard exterior-grade plywood for the riding surface.

What kind of wood is used for skate ramps?

The primary wood is birch plywood for the riding surface due to its strength, flexibility, and consistent grain. For structural substrate and framing, marine-grade plywood (BS1088) or exterior-grade plywood with phenolic glue is used. Specific skate-specific products like SkatePly incorporate a birch plywood core with a waterproof phenolic overlay.

What material is used for professional skatepark ramps?

Professional skateparks primarily use poured concrete for bowls and permanent features. For above-ground modular ramps, the standard is composite panels (Skatelite, Ramp Armour) over a marine plywood substrate, framed with pressure-treated lumber or steel. Some parks, especially in corrosive coastal environments, use all-aluminum ramp systems like those from RedRailed.

Is Skatelite better than wood?

For outdoor use, yes. Skatelite is dimensionally stable, waterproof, and requires no maintenance, whereas wood requires constant sealing and will eventually delaminate. For indoor use, the answer is more subjective; many riders prefer the feel and sound of birch plywood, but Skatelite offers a faster, more consistent surface that doesn’t wear down.

Before You Go

The main rule for material choice is this: climate is the project manager. If your ramp will ever see rain, sun, or snow, you are building an outdoor structure first and a skate ramp second. That means your material stack starts with water resistance, not preferred grip.

Your first step this week shouldn’t be buying wood. It should be deciding, definitively, where this ramp will live for its entire lifespan. If the answer is “outside,” then your shopping list begins with Pro Skate Composite, Skatelite, or SkatePly, not a sheet of birch from the local yard. That single decision filters every other choice, from the substrate to the fasteners. It’s the difference between a ramp that’s a seasonal project and one that’s a permanent part of the landscape.
