I'm looking to source steel specifically for trailer flooring, and I'm interested in dimensions of either 1500 x 2400 mm or 3000 x 1200 mm. It's essential that the steel meets durability standards suitable for heavy-duty use, as the trailers will be subjected to significant loads and various environmental conditions. Please provide information on availability, pricing, and lead times for these specifications. Additionally, any details on the types of steel you offer, including grades and treatments, would be helpful. I'm keen to understand your manufacturing capabilities and whether you can accommodate customization if needed. Looking forward to your prompt response.
