Buying Guide

Thickness and gauge

Choose sheet thickness based on load and shape: thin 0.025 in. embossed plates work for lightweight fenders, while heavier gauges resist denting and edge deformation

Pattern and traction

Embossed diamond/tread plate provides grip and hides scratches; select a raised pattern when slip resistance or visual texture is needed

Material and corrosion resistance

Use 100% aluminum alloy sheets for natural corrosion resistance and to avoid rust issues common with steel on trailer exteriors

Sheet length and seam planning

Match sheet length (common 10 ft runs) to fender dimensions to minimize seams and fasteners—longer lengths reduce joints but may require heavier handling

Mounting and edge finishing

Plan for proper edge folding, flanges, or hemmed edges to prevent sharp edges and to provide stronger fastening points for rivets or bolts
