美国采购需求：梯子

I'm interested in your foldable 14' ladder and would like more details on it. Could you provide me with info on its material, weight capacity, and any safety features? Additionally, I'd like to know about the available color options and if there are any specific certifications for quality. It would be great to get pricing details as well as any bulk order discounts you might offer. I'm also curious about the lead time for production and shipping. Looking forward to your prompt response so I can make a decision soon!
