Plastic or Metal Car Ramps: Which Is Better?

The short comparison

Plastic and steel ramps do the same job: they raise the front or rear of a car so you can work underneath. The difference is in how they are built and how that affects carrying, storing and long-term care.

Plastic ramps are usually molded polypropylene or similar polymer, often with a honeycomb inner structure. Steel ramps are fabricated metal, either a solid build or a hollow frame with a coating to slow rust. Neither material is automatically safer. What matters is the published rating, the condition of the ramp and how you use it.

• Plastic: lighter, no rust, often stackable or fitted with handles.
• Steel: can offer more lift height, but weighs more and needs rust care.
• Both: need a level surface, a matching weight rating and a careful driver.

How the specs compare

Here are five products from our spec sheet. All numbers are the makers' published specifications, and a dash means the maker does not list that value. Capacity is per pair.

Weight capacity and strength

Capacity is the first number to check. Ratings are given per pair, in pounds of gross vehicle weight, so compare them with your vehicle's gross weight and not only its curb weight. Across the 18 products on our best car ramps page, ratings run from 4,400 lb to 20,000 lb.

In that data, the plastic sets in the table above are rated higher than the steel set. That does not mean plastic is always stronger. It shows that a modern polymer ramp with a honeycomb structure can carry a rating that covers many cars, SUVs and trucks. Still, a rating is the maker's claim, so pick a pair with comfortable headroom over your vehicle's weight.

Steel has its own strengths. A solid steel ramp does not rely on molded ribs, and its shape is easy to judge by eye. Its weakness is corrosion, and a damaged coating or bent section needs attention.

Lift height, slope and fit

Lift height gives you working room. Among the models that list it on our page, lift runs from 2.44 in to 8 in. The tallest we list is the solid steel Garvee at 8 in, while the stackable TOWKING plastic ramp reaches 7.3 in with a 17 degree incline.

Slope matters as much as height. A tall ramp that is short in length climbs steeply, and a low car can scrape its bumper. Low profile plastic ramps such as the ROBLOCK, at 2.6 in of lift and 17.5 in long, are made for sports cars and other low vehicles. If you want an easier climb, look at ramp length and the listed approach angle, and see our best ramps for car comparison for more options.

Width counts too. A wider tread, such as the 12 in on the Ironton set, gives more room for wide tires.

Weight, storage and traction

Plastic wins on carrying. The ROBLOCK pair weighs 5.3 lb and the Ironton pair 20.6 lb, while the steel Garvee pair weighs 32.69 lb. If you move your ramps in and out of a garage every time, that difference adds up.

Storage is also easier with plastic in many cases. The TOWKING ramps are stackable, and the Florety ramps include carry handles. Steel ramps are usually simple one-piece shapes that do not nest.

Traction is the other half of the story. Rubber feet help stop the ramp from creeping forward as the tire pushes on it, and a textured surface helps the tire grip. Both matter most on smooth concrete. The Ironton and TOWKING sets list rubber feet, while the Garvee steel listing mentions an anti-slip structure but our spec row does not show rubber feet. Check the spec row for any pair you consider.

Which should you choose?

Use these steps to decide:

• Check your vehicle's gross weight and pick a pair rated above it.
• Look at ground clearance. A low car needs a low lift and a long, gentle slope.
• Decide how you will move and store the ramps. If space or carrying is a concern, lean toward plastic.
• Choose steel if you want the highest lift and are happy to inspect for rust and bends.
• Confirm rubber feet and a textured surface, especially for a smooth garage floor.

Safety notes

Ramps are only as safe as the way you use them. Park on firm, level ground, drive up slowly and straight, and keep someone out of the vehicle's path. Set the parking brake, put the car in park or in gear, and chock the wheels that stay on the ground.

Inspect every ramp before use. Look for cracks, deep gouges or white stress marks on plastic, and for bends, cracked welds or heavy rust on steel. Retire any ramp that looks damaged. Keep plastic out of long, direct sun when stored, since a maker may warn about heat and age.

Wear safety glasses when you are under or near a car, because dirt and fluid can drop. Never use ramps on gravel, soft dirt or a slope. Do not exceed the rating, and do not work under a car supported only by a jack.

Frequently asked questions

Do plastic ramps crack in cold weather?

Some plastics get more brittle as they age or in extreme conditions. Read the maker's guidance, store the ramps out of harsh weather, and inspect them for cracks before each use.

Can I use one ramp instead of a pair?

Ramps are normally used in pairs so the vehicle sits level. Some products ship as a single ramp, so check what is included and follow the maker's directions.

Should I put anything under the ramps?

Use a clean, hard, level surface. Rubber feet help, but a loose or soft base can still let a ramp shift, so avoid gravel or dirt.

Are ramps better than jack stands?

They suit different jobs. Ramps are quick for oil changes and inspections where the wheels stay on. Jack stands are needed when wheels must come off.
