How many of the six core materials of light steel villas do you know?
Compared with traditional cement buildings, light steel villas are a kind of villa residence that combines health and environmental protection, fashion and performance.
So, what makes it have so many advantages? Today, let's take stock of the materials of light steel villas on the market.
1. Light steel structural materials
2. Structural plates
3. Insulation, sound insulation, and fireproof materials
4. Waterproof materials
5. Exterior wall decoration materials
6. Roofing materials
1. Light steel structural materials
Alu-zinc plating: abbreviated as AZ150, galvanizing is 2-6 times more corrosion-resistant than galvanizing. The galvanized keel has no color change on the surface after long-term exposure. If it is corroded by chemical substances, a physical reaction occurs on the surface, and an aluminum protective film is formed on the surface of the keel, separating the external chemical substances from the keel, protecting the main material of the keel, and preventing rust. Therefore, high-quality manufacturers generally choose galvanized steel plates.
Implementation standards:
l Steel: AISI (American Iron and Steel Institute Standard)
l Construction: "Technical Specifications for Low-rise Cold-bent Thin-walled Steel House Construction"
l Zinc: ASTM (American Society for Testing and Materials Standard)
2. Structural Board
OSB Board
Oriented Strand Board is a directional structural board made of small-diameter wood, thinning wood, and wood core as raw materials and supported by a specific molding process. Because its strands are arranged in a certain direction, its longitudinal bending strength is much greater than the transverse one, which meets the structural material force requirements. It can be sawed, sanded, planed, nailed, drilled, etc. like wood. Better companies will use OSB boards with strong nail holding power, waterproof, fireproof, and formaldehyde-free.
10mm Calcium Silicon Board
Calcium Silicon Board, also known as Gypsum Composite Board, is a multi-material, generally composed of natural gypsum powder, white cement, glue, and glass fiber. Calcium silicon board has the properties of fireproof, moisture-proof, soundproof and heat-insulating. It can attract water molecules in the air when the indoor air is humid, and release water molecules when the air is dry. It can properly adjust the indoor dryness and humidity and increase comfort.
Picture
Cement fiber board
It is a building board made of siliceous and calcium materials as the main raw materials, adding plant fibers, pulping, copying, pressurization and curing.
A, A1 grade non-combustible material, no toxic gas release at high temperature
B, water absorption rate is less than 40%, and it does not deform when wet.
C, bending strength is greater than 20 MPa, not easy to be damaged and broken
3, thermal insulation, sound insulation and fireproof material
Formaldehyde-free environmentally friendly cotton
It uses natural rocks and minerals as the matrix raw materials, melts at high temperature, and adds an appropriate amount of binder after fiberization.
A, A1 grade non-combustible material
B, density ρ=800～1100kg/m3.
C. Thermal conductivity ≤ 0.044W/cm.k
D. Heat resistance ≥ 650 degrees
E. Excellent sound insulation performance
4. Waterproof material
Waterproof breathable membrane
The waterproof breathable membrane is made of polyethylene microporous membrane as the middle layer, and non-woven fabrics are used on both sides through hot melt direct pressing process. The middle layer is the main waterproof layer. The principle is that water vapor is in gas state, and the molecular particles are very small. It can pass through the microporous membrane through the diffusion principle to produce a breathable phenomenon. Liquid water or water droplets cannot pass through due to their surface tension, so it can prevent water penetration and play a waterproof function.
Self-adhesive waterproof membrane
It uses polymer resin and high-quality asphalt as the base material, polyethylene film and aluminum foil as the surface material, and uses a self-adhesive isolation layer. The product has extremely strong bonding performance and self-healing properties, and is suitable for cold construction in high and low temperature environments.
Waterproof coating
Waterproof coating is a solvent-based modified asphalt waterproof coating. Asphalt is used as the base material, and fillers, solvents, etc. are added and fully stirred to make a cold-construction waterproof coating. Convenient construction, easy material acquisition, suitable for various types of base buildings, evenly laid without dead corners, diversified colors, and smooth coating surface.
5. Exterior wall building materials
Metal carved board
Interior and exterior wall panels integrate insulation and decoration functions, and are a new type of exterior wall panels popular in the market in recent years. The surface is a high-quality color embossed metal plate treated with a special coating, the middle layer is a hard high-density polyurethane insulation section heat layer treated with flame retardant, and the bottom is an aluminum foil protective layer that plays a role in heat insulation and moisture resistance.
PVC exterior wall panels
PVC exterior wall panels are exterior wall panels made of polyvinyl chloride resin and auxiliary ingredients such as stabilizers. They have the characteristics of anti-oxidation, corrosion resistance, low price, energy saving and environmental protection, convenient construction, and little impact from seasonal changes.
Wood grain cement fiber panels
With cement as the adhesive component and an appropriate amount of plant fiber added, the cement fiberboard with wood grain on the surface has a more natural and beautiful appearance. It is durable, lightweight, heat-insulating, frost-resistant, sound-absorbing, fire-proof, mildew-proof, and ant-proof.
Cement fiber decorative board
Using cement material as the base material and composite fiber as the reinforcing material, it is mixed and processed into a flat plate with a certain formula and cured at high temperature and high pressure. The product is light, fire-proof, waterproof, mildew-proof, heat-proof, ant-proof, heat-insulating, sound-proof, impact-resistant, acid-alkali-resistant, aging-resistant, frost-resistant, and green and environmentally friendly. It is a high-end exterior wall decoration material that integrates functionality and decoration.
Artificial cultural stone
The texture, color, and texture of various naturally formed stones are upgraded and reproduced by artificial methods, and the effect is extremely original, natural, and simple. High-end artificial cultural stone has the characteristics of environmental protection and energy saving, light texture, rich colors, mildew-proof and non-flammable, good thaw resistance, and easy installation.
6. Roofing materials
Colored stone metal tiles
Using aluminum-zinc-coated steel plate as the substrate, after front and back protective film treatment, the surface layer uses non-toxic and harmless high-quality adhesives, and then covered with natural colored stone particles. Lightweight, high-strength, durable and easy to install.
Asphalt tiles
Using glass fiber felt as the base, after being dipped in high-quality asphalt, one side is covered with colored mineral particles, and the other side is sprinkled with isolation materials. It is a roofing material with decorative and waterproof functions. It has good waterproof and decorative functions, rich colors, various forms, and simple construction.
Colored steel corrugated tiles
Using colored layer steel plates, cold-bent into various corrugated corrugated sheets by roller pressing, it has the characteristics of light weight, high strength, rainproof, long life, rich colors, convenient construction, and maintenance-free. It has been widely promoted and applied.
Clay tiles
Made of wet blanks made of clay and other synthetic materials and then dried and fired at high temperature. The colors are rich and bright, not easy to fade, fireproof and long-lasting, the enamel surface is dense, which can prevent bacteria and dirt from being generated and entering. There is no odor and no harmful substances are released. It is easy to clean and does not require maintenance.
