We manufacture all common industry sizes of mud flaps and can produce any custom rectangular size you need for tractors, trailers, box trucks, straight trucks, and vocational equipment. Typical over-the-road semi sizes include 24″×30″ and 24″×36″, but we routinely build other formats (e.g., 18″×24″, 24″×24″, 30″×30″) to match specific equipment or branding goals. You can choose from multiple thicknesses—most commonly 1/4″ and 3/8″—in either rubber or poly to balance flexibility, durability, weight, and logo appearance. We can also match standard hole patterns or drill to your spec sheet so installation is fast and consistent across your fleet.
For custom rectangular flaps, simply tell us the width × height, material, thickness, and hole pattern (a drawing or photo works), and we’ll produce to spec. If you’re adding a logo, we’ll help size the print area so the artwork is crisp and visible at a distance without crowding the edges.
For irregular or contoured shapes—such as pickup or light-duty applications—our production team will review the design first. These parts sometimes require a template, extra fabrication steps, or different tooling to maintain strength at tight curves or mounting points. We’ll advise on minimum radii, best mounting zones, and any reinforcement needed so the flap performs on the road.
Whether you need standard 24×30 pairs for a trailer rollout or custom dimensions for specialty equipment, we’ll configure size, thickness, material, and hole pattern to fit your trucks—and your branding—perfectly.
Here’s how we handle it:
- Pass-through freight: We charge the real carrier rate—no hidden markups.
- Optimized pallets: Full or near-full pallets (around 200 flaps) ship more efficiently than partials (e.g., 50 flaps), which can lower your total cost even if the per-flap price is the same.
- Clear quotes: Your quote will show itemized product + tooling + shipping so you can compare apples to apples with any “free shipping” offers.
Ways to save on shipping:
- Order in pallet quantities or consolidate multiple locations into one shipment.
- Ship to a commercial dock (or a terminal hold) when possible to avoid accessorial fees.
- Plan reorders so we can combine production runs and minimize partial pallets.
Local pickup is also available from our central Midwest facilities if you’d like to use your own carrier or pick up yourself. Please note we don’t hold finished product on the dock—pickups must be scheduled promptly after completion.
Bottom line: Transparent, itemized shipping lets you control costs and often pay less overall than “free shipping” that hides freight inside the unit price.
