The prefabricated steel structure building has the advantages of large spanning capacity, lightweight, fast construction speed, no leakage, and long service life. Its outstanding feature is to adapt to unsupported spans, suitable for warehouses, workshops, factories, exhibition halls, breeding plants, auditoriums, libraries, classrooms, lecture halls, cultural and sports venues, bazaars, residences, prefabricated building etc.
Advantages
(1). Free to design architectural drawings for you;
(2). Features: Fast and flexible to assemble, safe, thermal and noise insulation, water proof and fire prevention;
(3). Cost-effective: Fast and easy installation greatly shorten the construction time which reduce the costs;
(4). Durability: The whole structure is easy in maintenance, which can be used for more than 50 years.
(5). Perfect design: Perfect design completely avoids leaks and water seepage. Meanwhile, it's also in line with the national level of fire prevention.
(6). Carrying capacity: can resists the impact of strong wind and seismic performance and bears heavy snow loads
1. Strictly control the welding position of the relative position of size , welding pass behind the prospective;
2. Reasonablly selection of welding parameters and order to prevent crack;
3. Electrode required drying, welding area need to clean up, welding process, together with the appropriate welding current, decrease of welding speed, gas completely escape , prevent the formation of weld porosity;
4. When continuously multi-layer welding, each weld layer after cleaning, prevent the formation of slag;
5. Selection for current, avoid arc pull too long, control electrode angle and arc method, avoid the generation of undercut.
