Fiberglass mesh reinforcement is a material of paramount importance in the construction and home improvement industry. It is widely utilized for its unique composition of glass fibers that are interwoven together to create a robust and flexible mesh. This mesh is then used to reinforce an array of surfaces such as drywall, stucco, and concrete. The primary aim of fiberglass mesh reinforcement is to amplify the strength and durability of these surfaces, resulting in increased resistance to cracking, chipping, and a variety of other forms of damage. The mesh is also designed to distribute stress and strain uniformly across the surface, improving its overall structural integrity. Moreover, this unique material is not only strong and durable but is also lightweight and simple to install, making it a go-to choice for professionals and DIY enthusiasts alike. In summary, fiberglass mesh reinforcement is a vital component that guarantees the security and stability of many building structures. Construction composite mesh is a product manufactured of corrosion-resistant composite basalt or fiberglass reinforcing rods of round section with a diameter from 2,5 to 6 mm crossing and fastened with each other at right angle. The sizes of formed cells can be 50×50, 100×100, 150х150 millimeters. The mesh is delivered in the form of special sheets (plates) with sizes 1500×380, 1500×500, 2000×500 and 2000×1000 millimeters. Occurrence of corrosion in steel reinforcement (due to influence of moisture or aggressive chemical environment) can finally lead to heavy degradation or complete destruction of the building. Concrete partitions, port structures, floors of industrial rooms and rooms with a high level of moisture are the structures of excessive risk. Set of the problems connected with use of metals in reinforcing structure drove the beginning of search of more multiple-purpose materials. The product of Composite Group Chelyabinsk company is a distinguishing composite fiberglass product among them.
