Product Description
We are specialized in deformed bar, which is also called reinforcing steel bar, rebar or ribbed steel bar. we also supply the thinner ones: 3-8 mm. our products are controlled strictly by our quality team. it's applied in a range of projects, such as building, housing, bridges, highway.
there are three pieces of deformed bar with ribs.
deformed bar with ribs can increase abrasion. they are made into wire netting to be used in constructions.there is a bundle of reinforcing steel in store.
reinforcing steel has so high tensile strength that it's usually made into concrete welded mesh.

in coil: 500 kg per big coil. 25 kg each coil, 20 coils bounded in one big coil. coil diameter: min. inner 300 mm, max. outer 800 mm.
in bars: 500 kg/bundle, length: 250 mm - 12000 mm.
note: we certify that the above materials comply with the specification standard. we could also produce as per customers standard.
in one container there are many rolls of reinforcing steel bars in 5 rows. each roll is packed with a layer of seaworthy plastic film.
reinforcing steel deformed bars are rolled with machine. they are packed with a layer of thick plastic to resist water and corrosion.there are several bundles of rebar, wrapped with steel strips. they are cut into the same length.
deformed bars are bounded with steel strips tightly. they are used in industrial construction.
feature of ribbed steel bar
saving cost: the tensile strength of cold rolled ribbed bar increases 1.5 times than raw material because of the process of plastic deformation after cold forming. as a result, under the same pressure, deformed bars are saved.
reduce loss: reinforcing bar in coil can not only improve productivity but also reduce losses with automatic machines.
non-flammable: when welding, burning, melting, sawing, brazing, grinding, or other similar processes, it's inevitable to projection out of flame. the ribbed steel bar won't hurt your health.
stability: steel products are stable in normal storage and operating conditions, except strong acid and alkali.
robust construction & abrasion resistance: the ribs increase the abrasion between rebar and concrete. combining with concrete, it makes the construction firmly.
easy installation.
applications
with high tensile strength and durability, reinforced concrete wire is widely used in a range of industries and applications, such as spring manufacture, wire forming, tie and lifting, wire mesh, wire netting, wire products, construction.
there is one roll of welded mesh made of galvanized steel bars.
thinner deformed bars with good durability could be welded into mesh and rolled together.concrete reinforcement column made of deformed bars are used in buildings.
deformed bars are high tensile strength enough to be used in buildings.

standard: the production of mesh reinforcement complied to bs 4483/sans 1024.
there are two sheet of concrete welded wire mesh. the top one is made by thinner wires, below with thick ones.
different sizes of concrete weld wire mesh are available. they are made by various wire diameters.on the left there is a big concrete welded mesh. on the right, it's details of mesh: top - welding point, bottom - diameter of the wire.
concrete welded mesh is made with accurate and uniform wires. these rebars are welded firmly.reinforcement steel bars are being welded into a mesh with machine.
concrete weld mesh is made firmly with machine. they are mainly used in bridge, road, housing foundations.reinforcement steel bars of different sizes are tied together firmly.
a large quantities of concrete welded wire mesh combined firmly make a strong foundation of construction.

note: other mesh sizes are also available.
concrete welded mesh can be designed either in flat sheets, rolls or bent to suit for your requirements.
there is a roll of concrete welded wire mesh.
concrete weld mesh made of thinner wires could be rolled so that it's easy to transport.there are many pieces of concrete welded mesh on wooden pallet.
thick concrete weld meshes are packed on one pallet.at construction site a piece of weld mesh is hang up with a machine. workers are preparing to catch it.
reinforcing mesh is installed with a machine. workers are building a strong foundation of the bridge.
advantage
firm structure, precise opening, corrosion-resisting and oxidation-resisting.
light and easy operation: it's light to be easier to move and lay on the concrete with machine.
better crack resistance: our thinner wires can effectively reduce the crack width between concrete slabs. distributing the stress in 2-way more homogenously, it controls crack propagation as well as the crack width.
application
due to good durability, high tensile strength and toughness, concrete welded mesh is applied in many areas, such as:
residential and industrial construction sectors: concrete floor slabs on fill, floor slabs reinforcement, suspended floor slabs, concrete wall, floor warming, brick wall reinforcement, power plants engineering.
railways and port infrastructures: tunnel, drains, box culverts, concrete roads, highway, dam, river bank protection walls, airport runways.
