galvanized trailer

Utilizing automotive chassis steel Q355B as the base material, a complete "inside-out" protective coating is achieved through a full-component hot-dip galvanizing process executed to European Standard EN 1461 (840°F molten zinc immersion), forming a zinc-iron alloy layer. This combines the high-strength load-bearing capacity of steel with the ultimate rust protection of the galvanized layer, making it a reliable choice for heavy loads and harsh environments.

Core Advantages

Comprehensive Rust Protection, Adaptable to Extreme Environments: The galvanized coating forms a metallurgical bond with the steel. It not only isolates the steel from oxygen and moisture but also features "sacrificial anode protection" – even if the coating is locally scratched, the zinc layer will corrode preferentially to protect the underlying steel substrate. In extreme environments such as seawater, muddy areas, and chemically polluted waters, its rust protection life can reach 15-20 years.

High-Strength Load-Bearing, Suitable for Heavy Loads: The steel frame, combined with square/ I-beam construction, is reinforced through precision welding and pull testing. Load capacity ranges from 0.5 to 18 tons, suitable for large vessels like yachts up to 50 feet.

Abrasion and Impact Resistant, Superior Durability: The zinc-iron alloy coating is hard, effectively resisting damage from road gravel impact, dock collisions, and friction during vessel loading/unloading, reducing the need for on-site repairs. Frame weld joints are fully covered by the galvanizing process, eliminating "dead-corner corrosion." Suitable for long-term outdoor storage and high-frequency commercial transport.

High Cost-Effectiveness, Controllable Long-Term Costs: The initial procurement cost is lower than that of aluminum alloy trailers of comparable specifications, and they require infrequent maintenance. Over a 20-year service life cycle, the comprehensive cost (including repainting and repair expenses) is only about 1/4 that of ordinary painted trailers. This makes them a highly cost-effective choice for commercial operations.

Application Scenarios

Vessels weighing 0.5-18 tons (e.g., yachts under 50 feet, commercial transport boats, flood control RIBs), long-term outdoor storage needs, complex road conditions with gravel/mud, high-frequency commercial transport (e.g., yacht clubs, shipyard docks).
