Fiberglass rod for agricultural small arch shed

图片
Mention of early rice seedling, thermal insulation film and support of bamboo; Today I’m going to share with you a new material instead of bamboo – Fiberglass rod . 1. Folding lightweight and high strength The relative density is between 1.5~2.0, only 1/4~ 5 of carbon steel, but the tensile strength is close to, even more than carbon steel, and the specific strength can be compared with advanced alloy steel. Therefore, in aviation, rockets, space vehicles, high pressure vessels and other products that need to reduce the weight of the application, have excellent results. The tensile, bending and compressive strength of some epoxy FRP can reach more than 400Mpa. 2. Good folding corrosion resistance FRP is a good corrosion resistant material, it has good resistance to atmosphere, water, acid, alkali, salt and various oils and solvents. Has been applied to all aspects of chemical anti-corrosion, is replacing carbon steel, stainless steel, wood, non-ferrous metals and so on. 3. Good foldin...
