A :scope of application
it is widely used in villas, urban flat to slope, residential quarters, hospitals, schools, civilian houses, civil construction, garden pavilion, shopping malls, tourist scenic areas, public buildings, large-span steel structure housing, activities, rooms and other areas of the roof.

B: product characteristics:

1. High strength
With a depth of 25mm stamping technology (domestic currently 17mm), which makes the products have good resistance to accidental load characteristics and voltage characteristics. At lower temperatures and annual snowfall in the area, even if it often has snow on the roof, it does not produce tile surface damage and fracture phenomena.
2. Shock seismic wind
With the ability to withstand impact attracting foreigners. Falling ball impact test that 1 kg of steel ball from 3 meters high free-fall does not produce cracks, the performance of low temperature impact performance significantly, simply installing the close connection with purlins, you can have a very strong wind and earthquake resistance capacity.

3. Corrosion resistance
In the long term resist acid, alkali, salt and other corrosive chemicals. Experiments prove that: In the salt, alkali and 60% following a 24-hour soaking in acid, it has not chemical reaction. It is Very suitable for acid rain-prone areas and coastal use, the effect particularly significant, and a variety of micro-organisms can not survive in the tile surface.
4. Durability
 Several times with anti-rust and anti-corrosion coating, in the natural environment with exceptional durability, even if the long-term exposure to UV, moisture, heat, cold, and impact . it was also able to maintain their color stability, 30 years without fading .
5. Waterproof and Fireproof
Substrate itself is non-combustible materials with excellent fire performance. As the length of the free extension of slope seamless connectivity, entire watt Tight integration with the fixed components of a complete sealing, lapping at combining tight, waterproof is very excellent.

und insulation warm and heat insulation

Sheet on the back of additional has special XPE, which makes the products have better sound insulation, heat preservation, heat insulation effect, and effectively to prevent condensation.

Bellow materials are general used in steel buildings , but we often customized each type depend on clients requirment .

Fixed packing, loading, transportation, unloading the matters needing attention:

(1) The lifting large there must be a person responsible for the use of fixture, suitable, strictly abide by the

rules of lifting, to prevent the occurrence of vibration, impact, deformation or damage, fall in the hoisting process.

(2) At the time of loading, there must be a special supervision, check car number and packing, the car pile

up securely, and to increase the necessary binding component loosening, prevent the loss.

(3) Remained stable in the transport process, the vehicle at the time of shipment, on the long, wide, high object transport, must be trained pilots, escort personnel responsible for, and mark is arranged on a vehicle.

(4) No rough handling, loading and unloading personnel handling, weight, size should be familiar with the components, and check the horse sling, rigging, prevent accidents.

(5) The member to the construction site, timely organization of unloading, stacking area.

(6) The crawler crane carrying member, should pay attention to the surrounding terrain, air condition, prevent the crawler crane overturning and component collision.

1. Common type of the industrial building?

Reply: Portal frame is the usual type in the industrial workshop and warehouse shed. Other types also could be designed and manufacturer as per clients’ request.

2. What’s the quality grade of the steel structure components?

Reply: Q345 is used for main steel structure, Q235 is used for secondary steel structure. 
3. How about the delivery time?
Reply: Usually,within 25-30 days after the order confirmed, also depends on the fabrication quantity.
4. How about the derust grade?
