Types of Running Boards and Their Specifications

Steel Running Boards

Known for their exceptional strength and load-bearing capacity, steel running boards are among the most durable options available. They are typically constructed from high-grade carbon steel and protected with either powder coating or stainless steel finishes to resist corrosion.

Stainless steel variants require minimal maintenance—regular visual checks for loose bolts or mounting brackets are usually sufficient. However, non-stainless steel boards need proactive care, especially in humid or salty environments. Applying rust inhibitor treatments periodically helps prevent oxidation. Additionally, inspect the powder coating regularly for signs of blistering or peeling; any damage should be repaired immediately to prevent underlying metal from rusting.

Aluminum Running Boards

Aluminum offers an excellent balance of strength, light weight, and natural corrosion resistance, making it a popular choice for modern SUVs like the Grand Highlander. These boards are often treated with anodizing or powder coating to enhance durability and aesthetics.

While aluminum doesn’t rust, it can corrode if the protective finish is compromised. Clean them using mild soap and water—avoid abrasive pads or harsh chemicals that could scratch the surface. Pay attention to fading or chalking on the finish, as this may indicate wear. Re-tighten mounting hardware every few months to maintain structural integrity, especially if frequently exposed to rough terrain or heavy use.

Plastic or Polymer Running Boards

These are cost-effective, lightweight, and naturally resistant to rust and corrosion. Made from high-density polyethylene (HDPE) or similar composite materials, plastic running boards are ideal for drivers seeking basic functionality without the weight or expense of metal alternatives.

However, they are less durable under heavy loads or extreme conditions. Over time, exposure to UV rays and constant foot traffic can cause surface degradation, warping, or cracking. They are best suited for light-duty use and should be replaced when significant wear is evident—especially if the step surface becomes slippery or structurally compromised.

Rubberized Running Boards

Typically built with a metal core (steel or aluminum) for strength and a rubberized top layer for grip, these boards excel in wet, icy, or muddy conditions. The textured rubber surface provides superior traction, enhancing safety when entering or exiting the vehicle.

Cleaning requires more effort—use a stiff brush and rubber-safe cleaner to remove embedded dirt and prevent mold or mildew buildup. Inspect the rubber layer frequently for cracks, peeling, or separation from the base. If the non-slip surface deteriorates, it can become a slipping hazard and should be replaced promptly.

Material Type	Durability	Maintenance Level	Best For
Steel (Powder-Coated)	High	Moderate	Heavy-duty use, off-road conditions
Stainless Steel	Very High	Low	Salt-prone areas, long-term durability
Aluminum	High	Low-Moderate	Balanced performance, all-weather use
Plastic/Polymer	Low-Moderate	Low	Light use, budget-friendly setups
Rubberized (Metal Core)	High	Moderate	Wet climates, enhanced traction needs

Essential Maintenance Tips for Grand Highlander Running Boards

Regular Inspection: Check your running boards monthly for signs of rust, corrosion, cracks, or loose hardware. Focus on mounting brackets and bolts, especially after off-road driving or winter conditions. Tighten any loose components to prevent wobbling or stress fractures.

Proper Cleaning: Wash running boards every two weeks with water and mild detergent. For steel and stainless steel, avoid abrasive scrubbers that can damage protective coatings. Aluminum boards should be cleaned gently to preserve the anodized or powder-coated finish. For rubberized surfaces, use a dedicated rubber cleaner and a stiff brush to maintain grip and prevent grime buildup.

Surface Repair & Refinishing: Address paint chips or peeling on steel boards immediately by sanding, priming, and repainting to prevent rust. If the anodized layer on aluminum is worn, consider professional re-anodizing or a new powder coat. Replace plastic or rubberized boards if the surface is deeply cracked or compromised.

Environmental Protection: In coastal or snowy regions, apply anti-corrosion sprays to metal components every few months. Parking in garages or using protective covers can reduce exposure to moisture, road salt, and UV radiation, extending the life of all running board types.
