As reinforcing material, plaster mesh is used for building internal and external decoration, especially in plastering work. It protects the surface of the plaster layer from cracking and increases the mechanical strength of the plaster layer. At the same time, the plaster mesh combines better with the plaster wall, forming a skeletal layer of plaster and putty, thus significantly strengthening the plaster layer and significantly extending its service life.
Due to its strength and durability, plaster mesh has also been successfully used as a reinforcement material for strengthening building foundations, repairing and reinforcing existing plaster, brickwork, installing insulation and roof tile joints, and paving road construction.
When choosing a plaster mesh, you must take into account its physical and mechanical properties, as well as its purpose. For example, glass fiber cloth for external plastering requires a mesh density of 160 to 300 g/sq.m.
Expanded metal is successfully used for underfloor heating installation and plastering insulation. Galvanized plaster metal mesh has high corrosion resistance. The use of galvanized mesh for plastering work can significantly extend the life of a house.
Plaster Metal Lath
When used for plastering, the plaster layer and the reinforced metal layer have different coefficients of thermal expansion. Therefore, subject to extreme changes in temperature, chicken wire (durable twisted woven mesh) is more acceptable for plastering than welded wire mesh or expanded metal. It has no risk of injury at work. Chicken wire plaster meshes are made from 0.6 - 2.0mm wire, mesh size from 13mm to 50mm.
We supply sheet metal lath in two types: diamond metal lath and rib meta lath. Flat diamond metal lath is not used over solid surfaces like gypsum, concrete, and wood sheathing. Because a flat sheet will only cause the stucco to bond only to the sheathing and not complete the embedding process. Therefore expanded metal mesh is usually self-furred: dimpled and V-grooved.
Chain link meshes with a maximum density of 3000 g/m 2 can be used for plastering external wall structures. It has high strength and is not affected by adverse factors. For interior plastering, on the other hand, a mesh with a density of 1300 g/m 2 (mesh size 10mm x 10mm, 15mm x 15mm) can be used.
Glass fibre cloth is resistant to corrosion, alkali and is light in weight. In general, fiberglass mesh exterior plastering helps to overcome stresses caused by humidity and extreme temperature changes. It has high resistance to stretching and tearing, protects surfaces from cracking, and improves mechanical strength. Its use helps to apply plaster perfectly and evenly.
Welded Wire Mesh
Without bends and welds, the lightweight expanded metal adds considerably to the strength and durability at a very low weight. Thanks to its rough surface, it combines well with putty, plaster and waterproofing materials, ensuring high quality and durable plaster coating for walls and ceilings.
Welded plaster mesh is made by welding mildly heat-treated wires with or without a zinc coating, helping to avoid cracking of the plaster layer in shrink walls. Galvanized mesh has a high resistance to corrosion and is more durable.
Plaster woven mesh is a square mesh fabric made from galvanized or non-galvanized low carbon treated wire (0.5mm-1.5mm diameter). It includes the black woven wire mesh and galvanized mesh. Woven plaster mesh is mainly used for reinforced rough plaster. It prevents crack shrinkage and increases the strength of the wall.
Since recent years, our company has been working in manufacturing metal mesh products for lots of safety protective industries. We are a leading manufacturer and distributor for metal mesh products and metal mesh deep processing products, which have excellent quality and superior reliability.
