BMC, SMC, GFK, GRP roofing materials are glassfiber reinforced plastic, also known as glassfiber roof, which are composed of resin and glassfiber. This kind of material owns a lot of special features that make it stronger than traditional roofing materials. Aobang composite roofing tiles is divided into: BMC roofing tiles, SMC roofing tiles, GRP roofing tiles, GFK roofing tiles. Excellent outdoor roofing tiles: BMC, SMC, GFK, GRP roofing materials Due to the excellent properties of BMC, SMC, GRP, GFK materials, it is the best choice for making roof tiles. BMC, SMC, GRP, GFK material is a composite material, mixed with polyester resin, chemical and mineral fillers, technical agents, usually reinforced with fiberglass. It is an excellent material for outdoor applications. It has weather resistance and UV stability and has a service life of more than 30 years in outdoor environments. It absorbs almost no moisture, so it can isolate the moisture from the outdoors to the room. It is water and chemical resistant so acid rain does not affect the surface of the roof. Colors are easily mixed into the BMC, SMC, GRP, GFK material as a pigment, so colored tiles can be easily obtained and the color does not disappear during its lifetime. BMC, SMC, GFK, GRP roofing materials ensure safe life BMC, SMC, GRP, GFK materials are also fire resistant. If there is no source of burning material around it, it will not spread and will immediately go out. Light weight and high strength are one of the biggest advantages of BMC, SMC, GRP, GFK materials. This material has a density of 1.7-2.0. It makes the tiles very light. Transportation costs, installation costs, etc. can be reduced. this materials make your roof tiles more colorful, longer lasting and more cost effective. What is gfk material Light weight high strength aging resistance UV protection acid and alkali resistance waterproof and moisture proof no fading low thermal conductivity energy saving. Why is GFK fiberglass so strong? Does GFK fiberglass has something special to make it strong? Since the orientation of the surface molecules is different with normal ones, the glassfiber gets to be stronger and more flexible. This change happened as it is withdrawn from the molten glass. This is the reason whay GFK fiberglass cannot be easily damaged. Find the great BMC, SMC, GFK, GRP Roof Tiles in Aobang! Aobang is a professional supplier of material GFK, BMC, SMC, GRP.

Ceiling is a kind of decoration on the top of living environment. In short, it refers to the ceiling decoration, is an important part of interior decoration. The ceiling has the functions of heat preservation, heat insulation, sound insulation and sound absorption. It is also the hidden layer of electrical, ventilation, air conditioning, communication fire prevention, alarm pipeline equipment and other projects. Aobang composite ceiling is divided into: BMC ceiling, SMC ceiling. Development of ceiling molding material The ceiling materials have been developed for more than ten years, and the technology is constantly being updated. The PVC ceiling is not resistant to high temperature, and it is easy to deform in a hot environment. The plastic steel plate is improved from the second generation of ceiling material PVC, which has the advantages of lower price, good thermal insulation and sound insulation, rich color and easy making and installation. However, according to the supervision and inspection results of the plastic sheet market by the Supervisory Office, the quality pass rate of plastic steel products on the market is only 40%, and the phenomenon of “water injection” in bending strength, coating thickness and alkali resistance is serious. Moreover, the plastic steel sheet has low strength, is easily twisted, is not environmentally friendly, has poor weather resistance, and releases toxic gases when burned. The physical properties of the composite material aggregate ceiling are very stable, and will not be deformed even if the water is long time. The composite ceiling is an excellent material for the ceiling and naturalization board in terms of strength and rigidity. The ceiling uses BMC,SMC,GRP,GFK bulk molding compound as a completely environmentally friendly material. BMC,SMC,GRP,GFK composite material ceiling advantages Beautiful, moisture-proof, easy to clean, excellent flame retardant effect, high strength, long life, high environmental protection, easy installation, moisture-proof and waterproof, heat insulation, corrosion resistance, tight connection, oxidation resistance, anti-aging, no deformation, high strength, Light and tough, with natural texture and wooden texture, a variety of colors, natural and beautiful, with a variety of specifications, size, shape, thickness, the same processing properties as logs, no pollution, recycling, no cracks, no expansion, no deformation, no maintenance, no mold, anti-corrosion, anti-insect, anti-termite, energy saving. What is important is the low material cost of BMC,SMC,GRP,GFK molding compound, making it a cost-effective ceiling material than such as steel-plastic panels, aluminum gussets, and aluminum alloys. The visual effect is soft, feels good, high strength, flame retardant, fireproof, and has strong weather resistance. Excellent insulation and heat insulation performance, which overcomes the poor thermal insulation performance of traditional ceilings. Good water resistance, no corrosion, no deformation, no fading and no other undesirable phenomena in a humid environment. Excellent sound absorption, it is a good sound insulation material, suitable for public places such as medium and high-grade office buildings and large conference halls. Lifetime usage of the BMC, GFK, GRP, SMC Ceiling A competitive good point of the BMC, GFK, GRP, SMC Ceiling is that you can use it for 25 to 30 years without any sign of breaking or deterioration. Researches show that, a BMC, GFK, GRP, SMC Ceiling’s estimated lifetime is 28 years. The BMC, GFK, GRP, SMC Ceiling has no obvious weak point, and since it is fire-proof and chemical-proof, it would not easily damaged by man. BMC, GFK, GRP, SMC Ceiling is the environmentally friendly choice Compared with other ceiling materials, one important aspect of BMC, GFK, GRP, SMC Ceiling is that it’s environmentally friendly.

RILICO Plywood is a material made from slim layers or "plies" of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to each other. It is an engineered wood from the household of manufactured boards which include medium-density fibreboard (MDF) as well as fragment board (chipboard). All plywoods bind resin as well as wood fiber sheets (cellulose cells are long, strong as well as slim) to form a composite product. This alternation of the grain is called cross-graining and also has several vital advantages: it minimizes the propensity of wood to divide when toenailed at the edges; it reduces expansion and contraction, offering boosted dimensional security; and it makes the strength of the panel constant throughout all instructions. There is generally a strange number of plies, to ensure that the sheet is balanced-- this lowers bending. Due to the fact that plywood is adhered with grains running against each other as well as with an odd number of composite components, it has high stiffness perpendicular to the grain instructions of the surface ply.
