美国采购需求：梯子

I'm interested in obtaining a quote for the folding ladders that your factory produces. Specifically, I'd like to know the pricing for different order quantities, as well as any available discounts for bulk purchases. It would be helpful if you could provide a breakdown of the costs, including any additional fees for shipping or customization options. Additionally, I'd appreciate information on the materials used in the construction of the ladders, their weight capacity, and any safety certifications they may have. If you also have catalogs or brochures with product specifications and available colors, that would be great. Looking forward to your prompt response so we can potentially move forward with an order!
