The steel structure produced by Dalian Guangtong Steel Structure Co., Ltd. has the advantages of light weight, high strength, good overall stiffness, corrosion resistance, environmental protection and energy saving. The eight key points of steel structure design and construction of workshop of Dalian Guangtong Steel Structure Co., Ltd. are as follows:

1. Bearing capacity

The workshop steel structure bears construction load, rain, dust, snow pressure and maintenance load. The load-bearing performance of metal roof panel is related to the cross-section characteristics of the plate type, the strength and thickness of the material, the way of force transmission and the spacing of purlins (auxiliary purlins).

2. Lighting

The building area of the workshop steel structure  is generally large. In the daytime, the skylight is used to improve the indoor lighting and save energy. The service life of the skylight should be considered to coordinate with the metal roof panel when the daylighting board or daylighting glass is arranged at the specific position of the metal roof, and the waterproof treatment should be done at the joint of the skylight and the metal roof panel.

3. Damp proof

Especially in the rainy season in summer, prevent the condensation of water vapor in the metal roof bottom layer and metal roof layer, and drain the water vapor in the metal roof layer. The solution is to fill the insulation cotton in the metal roof layer, lay the waterproof membrane on the metal roof bottom plate, and have ventilation nodes on the metal roof panel

4. Lightning protection

There are many thunderstorms in summer. When designing the steel structure room of workshop, lightning must be led to the ground to prevent lightning from penetrating the metal roof and entering the room.

5. Fire prevention

In the process of using workshop steel structure, fire is a big hidden danger, so fire prevention measures should be taken. When the steel structure of the workshop is in fire, the metal roof material will not burn and the flame will not penetrate the metal roof panel.

6. Anti seepage

In addition to leakage prevention, the steel structure of the workshop must also prevent rainwater from seeping into the metal roof panel from the outside. Rainwater mainly enters the metal roof through lap joints or nodes. In order to achieve the function of anti-seepage, it is necessary to use the sealing washer at the screw opening and then adopt the hidden fixation, use the sealant or welding treatment at the overlap of the plate, preferably use the full-length plate to eliminate the overlap, and use the waterproof treatment with tight abdominal distension at various joints.

7. Sound insulation

The general workshop steel structure is mostly used in the production workshop. In the process of production and construction, it is inevitable that there will be noise. In order to prevent the sound from outside to inside or from inside to outside, the workshop steel structure is designed. The sound insulation material (usually heat insulation cotton) is filled in the metal roof layer, and the sound insulation effect is expressed by the sound intensity difference dB on both sides of the metal roof layer. The sound insulation effect is related to the density and thickness of the sound insulation material. It should be noted that the sound insulation materials have different blocking effects on different frequencies of sound.

8. Heat preservation

Do a good job in summer rain work, on the other hand, we should also do a good job in winter insulation. To prevent the heat transfer on both sides of the steel structure metal roof of the workshop, so as to stabilize the indoor temperature. The thermal insulation function is realized by filling thermal insulation materials (commonly used glass wool and rock wool) under the metal roof panel. The thermal insulation effect is expressed by U value, and the unit is w / m2k. The thermal insulation performance is determined by the following factors: the raw material, density and thickness of the thermal insulation cotton; the humidity of the thermal insulation cotton; the connection mode between the metal roof panel and the substructure (to prevent the "cold bridge" phenomenon); the repeated ability of the metal roof layer to the thermal radiation.
