When designing a steel structure workshop, some factors should be considered for the best design. The costs include but are not limited to:

Anti-seepage: Prevent rainwater from seeping into the metal roof from the outside. Usually, rainwater enters the metal roof through overlapping seams or nodes. In order to achieve the anti-seepage function, a sealing washer should be used in the screw port, and then it should be hidden and fixed. Where the panels overlap, a sealant or welding treatment should be applied to eliminate overlap.

Fire protection: In case of fire, it must be ensured that the metal roof material will not burn and the flame will not penetrate the metal roof.

Windproof: Considering the maximum local wind pressure, the design of the steel structure workshop should ensure that the metal roof will not be pulled apart due to negative wind pressure.

Sound insulation: prevent sound from spreading to the room or from the room to the outside. Generally, insulating material will be filled between the layers of the metal roof panel. The sound insulation effect is highly related to the density and thickness of the sound insulation material.

Ventilation: Considering indoor and outdoor air circulation, ventilation openings should be provided on the roof structure of the building.

Moisture proof: Prevent water vapor from condensing on the top metal layer. The solution is to fill the roof slab with insulation cotton and paste the waterproof membrane on the roof slab.

Load-bearing: The steel structure shed workshop should have a large load-bearing capacity, can withstand heavy rain and heavy snow, and withstand the load of construction and maintenance.

Lightning protection: Prevent lightning from penetrating the metal roof and entering the room.

Lighting: Skylights can be used to improve indoor lighting during the day. It can be a lighting panel or glass.

Control thermal expansion and contraction: Taking into account certain areas with large temperature differences, it is necessary to ensure that the metal top plate will not be damaged by the stress caused by thermal expansion and contraction.

Advantages:

1. Prefabricated: Fast and easy installation, save time and labor;
2. Customized design: different size, various layout, shape and appearance;
3. Light weight: lighter than concrete;
4. Removable
5. Environmental Friendly: recyclable, no waste produced;
6. High strength: can resistance grade 8 earthquake, water proof, fire proof, can resist strong wind and heavy snow.
7. Long life span: more than 50 years.
8. Wide span: single or multiple spans, maximum span 60m without middle columns.
