Steel mesh - application and classification
Steel woven mesh is one of the most popular and recognizable segments of the rolled metal market. Literally any fencing - from private properties to industrial zones and partitions for various purposes - is made of steel woven mesh. Fences, and not only steel woven mesh, which you can buy from the Rent Metal company at a competitive price, is applicable in various fields:
- Construction – as a reinforcing frame during insulation work, as a sieve for sifting building materials, for strengthening road asphalt pavement, production of reinforced concrete light-load structures;
- Mining - strengthening mines and mines, also sifting - separating materials into fractions;
- Agriculture – production of cages, enclosures and partitions for rabbitries and poultry houses.
Chain-link mesh, price which is indicated per meter, can be delivered throughout Moscow and the region without coating, with the application of zinc or polymer coating. Protecting the mesh from external influence environment allows you to successfully operate it for ten years without changes appearance. Resistance to corrosion, resistance to temperature changes, manufacturability and ease of installation - steel mesh is in very wide demand and the possibilities of its use are constantly expanding.
Steel woven mesh GOST 5336-80 – production and characteristics
GOST classifies steel woven mesh according to the accuracy of cell dimensions, coating and cell shape. The mesh is a fabric with square or rhombic (diamond angle 60°) cells, twisted from flat or round spirals woven into each other in a sequential order. Manufacturing material – low-carbon steel wire, thermally untreated or galvanized. Protective zinc coating is applied in several ways - hot or galvanic. Hot-dip galvanizing is carried out in stages - cleaning, degreasing, washing and drying, then immersion in a zinc bath. Steel mesh coated in this way is used for a wide range of construction work and is characterized by durability and resistance to corrosion.
Galvanic coating is the application of a layer of zinc by electrochemical action on metal; as a result, the coating is smooth, without the slightest defects and retains its original appearance for a long time.
Produced from wire with a cross-section from 1.2 mm to 5 mm, quality requirements: adjacent spirals are woven with all turns, there are no inverted spirals in the mesh. Rolls are supplied weighing no more than 80 kg; a roll weight of 250 kg is acceptable for some types of mesh. The length of the roll is no more than 10 meters, in agreement with customers it is possible individual order, roll width up to 1.5 meters. The ends of the roll are wrapped either in canvas or paper, the rolls are tied with rolled wire or tape.
