Color steel plate coating is cold rolled steel plate, galvanized steel, surface chemical treatment after coating (roll coating) or composite organic film (PVC film, etc), and then cured by curing and made of products. Also some people call this product "pre roll coated color steel plate", "plastic color steel plate". Color plate products are manufacturers in the production line into a volume production, it is also known as the color coated steel coil. Color steel plate not only has high mechanical strength, easy molding performance, but also has a good decorative coating materials and corrosion resistance. Color steel plate is a new material which is respected in the world today. With the progress of science and technology, enhance the awareness of the environment, improve people's living standards, color plate activity room shows more and more strong vitality and broad market prospects, by construction, household appliances, electronics, transportation, interior decoration, office equipment and other industries favored.
The color steel plate movable house has the advantages of light weight, high strength, heat preservation and heat insulation, beautiful appearance and durability. Color steel plate movable house construction cleaning, widely used in large span workshop, warehouse, office building, villa, the top floor of the building, air purification room, cold storage, shops, kiosks and temporary room. Light color steel plate core sandwich plate square meter weight less than 14KG can fully reduce the structural load, reduce the cost of the activity room structure.

Disadvantages of steel structure workshop:
One, steel structure workshop foundation is easy to lose stability
Due to the characteristics of the steel structure itself will be the overall instability or local instability, is related to the whole process of foundation and bolt, both are interrelated, most steel structure instability is caused by steel, once pressed parts and bending parts of the long
Fine ratio exceeds the standard value, it will lose stability. The objective factors that lead to instability are more effective, such as the load change, the initial defect of steel, the different support conditions will lead to instability. The foundation problem is divided into the foundation strength problem, the foundation deformation
Three kinds of problems and basic damage.
1, the strength of the foundation is generally manifested in the foundation, the foundation bearing capacity is insufficient, the foundation or slope stability.
2, the problem of foundation deformation is concentrated in the soft soil, wet and unfamiliar loess, expansive soil and seasonal frozen soil and other regions, these regions due to the load of foundation deformation and uneven settlement.
3, the foundation of the destruction of the form to live there are three forms of presentation, local shear failure, the overall shear failure and punching shear failure.
Two, steel structure factory steel roof damage
1, the majority of steel roof reconstruction is composed of thin wall C steel and slender rods, the shape of the cross section is complex, and the stress concentration of the joints also has eccentric gravity.
In 2, steel roof design, load calculation and the calculation model is correct and the calculation is close to the limit state, the structure bearing capacity of the minimum safety, humidity, overload and corrosion is very sensitive, it is easy to cause the loss of chance factors
Effect, if the manufacturing, installation and use of a variety of negative effects in the process of adding into the steel roof is the most serious damage to the steel structure of the plant parts.
3, the occurrence of failure of the main rod bending, roof collapse, the joint plate bending or cracking, frame member rupture, roof flexure roof support buckling, internal sink leakage and so on.
Three, steel structure factory steel corrosion
Steel structure workshop is exposed to the outside, not strong corrosion resistance of ordinary steel, especially humidity, a corrosive medium under the external environment, the steel structure is easy to rust corrosion, the bearing capacity greatly weakened. A large number of statistical data show that Because of the corrosion of steel roof truss, and lack of maintenance caused the collapse accident than in the total accounts for a large proportion.
