Product Description:

Steel structure project is the third generation construction. It combines H section and c/z section into the frame with the profiled steel sheet or sandwich panel as the wal and roof. The traditional reinforced concrete construction has aready been taken place by this kind of construction in developed contries. It has many excellent charateristics such as light weight, larger span, less marerial, low cost, less foundation, short building cycle, safe, beautiful, ect. It is widely used in single industrial factory, warehouse, business construction, office, parking lots, residence and so on.


Steel structure office building  fabrication process:

1. Prepair raw materials : cut steel plate or use internation size H section steel and angle steel,round tube,round steel,square tube etc.;

2. Assembly and welding: our welders will follow the drawings to assembe the steel members and weld them together as a entire beam/column/brace and so on; (Our quality inspector will check the steel pieces after finish welding,this is the first quality check)

3. Sand blast : After finish welding and polishiing,our sand blast effect can reach internation 2.5 high grade,very good for resist rust;(Secondary quality check)

4.Paint : Within 2 hours after sand blast,all the steel members should be paint. Client can choose any color and any brand of paint.(The third quality check)

5. Inspect the goods by client : After we finish a part of fabrication work,we will invite clients to check the goods before we pack the steel frame.

6.Packing and loading : If clients require us to load the goods by close containers,we will pack the steel structure members one by one on the steel skid and tie the whole steel package well.(The fourth quality check )

Q:How many square meters is one ton of steel structure anticorrosion?
The whole system of 2000 quotas, including 2000 quotas, has no relevant explanations. Neither has been cancelled nor has it been made clear.
Q:How to calculate the allowable slenderness ratio of steel structures under compression?
The slenderness ratio is in the majority of cases for the component, and the formula coffee has given. As for the concept, it is easy to see from the formula that the slenderness ratio is the ratio of the length of the member to its corresponding radius of gyration.
Q:What are the methods of steel structure rust removal, which method is good?
3, hand powered derusting, namely: the use of hand-held electric tools or sandpaper, Fengchan and other tools in the surface rust of steel structure; 4, flame cleaning: the flame surface concentration, because of rust and steel of different thermal expansion coefficient and the two separation.
Q:How can steel structures be made from bolts or bolts? High strength bolts are generally used for installation or production?
It should be said that the steel structure is made unless a small number of bolts are used for positioning in the process equipment and the bolt is removed after completion of the assembly. All other bolts are mounting bolts, including high strength bolts. The production process does not use high-strength bolts, high strength bolt than ordinary bolt because of high cost and high strength bolt cannot be used for the two time in technology (because of the bolt torque coefficient needs to be determined, determination of the torque coefficient is discarded).
Q:What plate is the slab below the concrete floor of the steel structure?
Under cantilever conditions, the deck plate acts only as a permanent template. The length of the cantilever can be determined according to the sectional characteristics of the floor support plate. In order to prevent the cracking of the cantilever, it is necessary to place the negative reinforcement at the base of the structure according to the design of the engineer.
Q:Steel structure brush fire retardant coating per square meter kg?
The amount of fire retardant paint is determined according to the coating thickness of fire-resistant coating, and the indoor thin steel structure fire retardant coating: the fire resistance limit of 2.5 hours per square meter is 6kg. Fire resistance limit of fire resistance limit of fire resistance limit of 2 hours per square meter was 4.5kg for 1.5 hours the amount per square meter 2.5kg 1 hours the amount per square meter 1.5kg indoor ultra-thin fireproof coating for steel structure: the fire resistance limit of fire resistance limit of fire resistance limit of 2 hours of consumption per square meter 3.5kg 1.5 hours per square meter per hour amount 2.9kg 1 the amount of 1.6kg square meters of indoor thick fire retardant coating for steel structure, fire resistance limit of 3 hours per square meter was 23kg. 2..0 hours of fire resistance per square meter dosage of 14kg
Q:What does LL represent in steel structures?
Common steel girders may be floor beams or other common beamsIn terms of frame beams
Q:What is a steel structure?
Steel structure is mainly made of steel material. Mainly used in bridges, buildings, lighthouses, boats and other fields. In addition to the steel structure, there are wood structure, concrete structure, brick concrete structure and so on.
Q:Who knows what HW, HN and HM mean in steel structures?
TM, TN, TW also refers to the middle flange, narrow flange, wide flange, T steel, in which the width of the wing refers to the flange width, B= section height H, mid wing refers to B= (1/2~2/3) H, narrow wing refers to B=1/3~1/2H
Q:What does steel structure "Zhongshan wall post" mean?
The utility model is provided with a reinforced concrete structural column resisting the horizontal wind load in the gable of both ends of the brick concrete structure, and is simply called a wind resistant column. A reinforced concrete beam that connects the wind column in the horizontal direction and acts as an integral reinforcement is referred to as a wind resisting beam. Generally used for high-rise, large internal space, less walls of brick concrete structure housing, such as industrial plants, large warehouses and so on.
