Here, I suggest that if the warehouse has a certain height and the goods stored are light, you can choose to build an attic platform. The attic platform is supported by shelves and can be designed into multiple floors (generally 2-3 floors). Provide stairs, handrails and elevators. This is a simple shelf to make full use of space. Build a middle attic on the existing shelf or workplace to increase the storage area. General light bubbles, small and medium-sized goods or goods with long storage period can be placed on the attic floor, and the goods can be lifted by forklift, conveyor belt, hoist, electric hoist or lifting platform. Suitable for high warehouse, small goods, manual access and large storage capacity. The floor support frame has complete varieties and specifications, and the attic floor has flat plate, diamond plate, steel chrome plate and wood plate. In the attic, light carts or trays are usually used to pull carts.
