Q: Will light steel rust?
A: Depending on the material, light steel is also divided into types, Two kinds of keel steel materials are commonly used in the market: G550 AZ150 and Q550 Z275, which represent the two types of Australian standard and American standard respectively. Among them, 550 represents the value of the yield point, that is, if it reaches this strength, it will deform, but if it is an overall structure, it cannot be judged only by the value of a single material, AZ150 means galvanized 150 grams/square meter, Z275 means galvanized 275 g/m².
The coating of the product is the biggest deciding factor
Galvanized
The weather resistance of galvanized strong acid and alkali environment is more than 1500 hours. This kind of steel is the standard material for most two-plate and one-core light steel villas. As the main material with the largest amount of housing, because of its cheap price, the overall cost of the house is relatively low.
Galvalume
Aluminum-zinc plating is 2-6 times more anti-corrosion than galvanizing. The long-term exposed surface of the aluminium-zinc keel has no colour change. Spaced to protect the keel body material and prevent rusting. Its strength is ≥9, the weather resistance in strong acid and alkali environment is ≥5500 hours, the natural environment conditions can be used for at least 90 years, and the service life is 275 years as tested by the university professional laboratory. The price is relatively expensive.
Galvanized is more resistant to corrosion and embroidery.
If some light steel contractors choose inferior steel, it is much more difficult to prevent rust.
Q: Is light steel warm in winter and cool in summer?
A: Yes, but depends on its wall material. The contractors use good thermal insulation materials to build light steel villas, so there is no need to worry about thermal insulation. If it is a cold north, even if heating and floor heating are installed, it will be warmer than ordinary houses.
XPS Insulation Board
XPS insulation board may sound unfamiliar, but it has many advantages: not only very little water absorption but also very compressive, almost no ageing in normal use, it can be said to be an ideal material for building insulation.
Glass Wool
Belonging to a category of glass fibres, it is a man-made inorganic fibre. Glass wool is a kind of inorganic fibre by clarifies molten glass to form a cotton-like material. The chemical composition is glass. It has good moulding, low bulk density, high thermal conductivity, thermal insulation, good sound absorption, corrosion resistance and stable chemical properties.
Plasterboard
A material made of building gypsum as the main raw material. A building material with lightweight, high strength, thin thickness, easy processing, sound insulation, heat insulation and fire resistance, etc.
Conclusion: Under the same thermal insulation effect, the thickness required by various materials is different, and the effect achieved will be different.
