加拿大采购需求：气弹簧、尾门助力器、气撑杆、气减震器、气升降器、气活塞

I'm reaching out to gather more info on your Murphy bed fitting components and associated hardware kits, as I'm exploring options for a potential purchase. Could you please provide detailed specs, including materials, dimensions, and weight limits? Additionally, I'd appreciate insights on any unique features or benefits your products might offer. Furthermore, could you share your pricing structures, minimum order quantities, and lead times for availability? It would also be helpful to know about any bulk purchase discounts or ongoing promotions. I'm looking to make an informed decision soon, so any prompt details you can provide would be greatly appreciated.
