HECASA Tandem Axle Diamond Plate Fenders
These heavy-duty tandem axle fenders are designed for 13″–15″ tires and feature a steel diamond plate surface for enhanced protection against road debris. The 10-1/4″ width and 72-7/8″ length provide extended coverage, reducing splash and shield damage during loading and unloading of equipment. The 13″ tall profile adds clearance for various trailer configurations, while the Q235 steel construction offers durability for long-term use. This option is well-suited for landscaping, cargo, and car-hauler trailers that see frequent equipment interaction.
ToughGrade Round Steel Trailer Fenders
Round steel fenders designed for single-axle trailers, available in a double-pack or single option. Measuring 10″ wide, 32″ long, and 15″ tall, they provide ample coverage for most 13″–15″ tires. The fenders ship primed and are ready for paint to match your trailer’s color scheme. Their slightly rounded sides create a flat welding surface, simplifying installation and offering strong support for heavy loads. This option balances ease of welding with broad tire compatibility and a clean, industrial appearance.
(2) TRAILER FENDER STEP DIAMOND PLATE 11ga Weld On Corner
This 11-gauge diamond plate corner set is specifically designed for weld-on installation, providing a rugged step-ready corner with a 3/4″ 90-degree lip. The 8″ x 8″ footprint keeps installation straightforward while delivering durable support for trailer steps. A practical choice for trailers that frequently load and unload at varying heights, this corner piece improves safety and ease of access, especially on utility and landscaping trailers.
HECASA Square Axel Trailer Fender 14″–16″
HECASA’s square fender is tailored for 14″–16″ tires and uses a 16-gauge steel sheet with CNC folding for improved durability. The design includes a 90-degree edge on one side and a substantial footprint of 32″ L x 9″ W x 13″ H. This fender pairs a modern aesthetic with robust performance, offering effective tire protection while supporting straightforward welding and integration on utility or landscape trailers that handle heavy loads and frequent side impacts.
D2E Trailers Tandem Fender With Backplate
The D2E tandem fender showcases a 10″ x 72″ x 19″ dimension paired with a 14-gauge treadplate backplate, designed for heavy-duty tandem axle trailers. The treadplate backer adds rigidity and a welded-on surface that helps distribute impact loads. Buyers should be aware that multiple fenders ordered may not arrive concurrently, and some surface rust is possible due to humidity at delivery. This option emphasizes resilience and structural integrity for frequent loading of equipment and cargo on rugged trailer setups.
Set Of Tandem Trailer Axle Fender Backs
This set provides backings for tandem-axle applications, made from heavy-duty steel with a 16-gauge thickness. The weld-on installation option simplifies mounting, and the non-painted finish allows users to coat the backs to match their trailer color or protective coating. Designed to fit 9×72″ and 10×72″ fenders, the pre-cut design ensures an exact fit inside the fender recess, helping ensure a clean, durable assembly.
Trailer Fender Step Diamond Plate Corner 11ga 4-Pack
This four-piece set mirrors a robust 11-gauge diamond plate configuration with a welded-on corner design. Measuring 8″ x 8″ x 11″ with a 3/4″ lip, these components provide reinforced corners and stepped access. The extra pieces enable flexible coverage on trailer edges or to retrofit existing fenders with additional, welded-in protection. This option suits builders seeking consistent, step-ready corners across multiple fenders.
RecPro Trailer Round Steel Fenders (2 Fenders)
RecPro’s round teardrop fenders are built from 14-gauge galvanized steel, ensuring higher durability and weldability than thinner options. The design prioritizes a welding-friendly shape and a sturdy build for weld-on installation. These fenders measure 36″ long, 13″ high, and 20″ deep, providing substantial coverage and protection for wide trailer tires. They are a reliable choice when selecting a heavier, corrosion-resistant fender for frequent use on rugged job sites.
Buying Guide: Key Purchase Considerations
- Material and gauge: Higher gauge steel (e.g., 14–16 gauge) typically offers better impact resistance and weldability, but adds weight. Diamond plate surfaces enhance abrasion resistance and debris deflection.
- Fitment and tire size: Confirm compatible tire diameters (commonly 13″–16″) and axle configurations (single vs. tandem) to ensure adequate coverage and clearance.
- Weld-on compatibility: Some fenders are specifically designed for weld-on installation, while others may require different mounting methods. Ensure your trailer frame and fender backs support weld-on mounting to avoid compatibility issues.
- Backplates and reinforcements: Backplates add rigidity for tandem axles and heavy loads. Consider treadplate backplates for extra protection where debris impact is common.
- Finish and coating: If the fenders are unpainted or primed, plan for painting to match the trailer and to protect against corrosion. Non-painted bases can simplify color matching but require additional coating steps.
- Weather and humidity considerations: Some items may arrive with light surface rust or require immediate post-delivery tack-down adjustments. Proper storage and timely installation help mitigate issues.
- Number of pieces and set options: Some listings offer multi-fender packs or corner pieces. Ensure you’re purchasing the exact quantity and configurations needed for your trailer’s length and axle count.
- Installation effort and tools: Weld-on fenders demand safe welding practices, appropriate equipment, and potentially structural reinforcement. Plan for a clean, level mounting surface and proper ventilation during welding.
- Brand and warranty: Reputable brands with clear product specifications tend to deliver consistent fit and durability. Review any available warranty or return policy for the selected fenders.
When selecting weld-on fenders, balance wire-to-frame compatibility, coverage height, and ease of installation with the intended trailer use. For frequent heavy-duty hauling, prioritize thicker steel, broader coverage, and reinforced backplates. If you require quick installation and simple customization, rounded or square profiles with primed finishes offer straightforward welding and painting workflows.
