1. Application
application in the fields of industrial and civil building floor, roof beam column, wall, concrete pavement, bridge deck pavement, airport runway,tunnel,culvert, dock floor,precast etc
2. Bar diameter
4-14mm
3. Classification
Cold-rolled ribbed mesh, cold-drawn smooth round mesh and hot-rolled ribbed mesh, among which cold-rolled ribbed mesh is the most widely used
4.Features
<1>Significantly improve the quality of steel reinforcement engineering
<2>Significantly improve the construction speed
<3>Strengthening the crack resistance of concrete
<4>It has better comprehensive economic benefits
Advantages of cold-rolled ribbed mesh:
1. High steel strength can save construction steel and reduce engineering cost.Grade LL550 cold rolled ribbed steel bar compared with hot rolled round steel, used in cast-in-place structure (especially LouWu cover) can save 35% 40% ─ of steel.If consider need not bend hook, steels managing a quantity to need more.According to the current steel market prices, each use of a ton of cold-rolled ribbed steel, steel costs can save about 800 yuan.
2. Good bonding and anchoring performance between cold-rolled ribbed steel mesh and concrete.Therefore, it can be used in the components to fundamentally eliminate the phenomena of cracking in the anchorage area of components and damage caused by steel wire slip, and improve the bearing capacity and crack resistance of the end of components.In reinforced concrete structures, the crack width is also smaller than that of plain round bars or even hot-rolled threaded bars.
3, cold rolled ribbed steel mesh elongation than similar cold - processed steel.
Cold rolled ribbed steel bar in prestressed concrete members, is the upgrading production of cold drawn low carbon steel wire, in cast-in-situ concrete structure, can be substitution reinforcement, in order to save steel, is better one in the same kind of cold rolled steel.
The cold-rolled ribbed reinforcement network is a kind of rebar with two or three crescrossed surfaces formed by hot rolled wire rod through multiple cold-rolled reducing diameters, one rib compression and elimination of internal stress.
Cold drawn round wire mesh
Cold drawn round steel bar welded mesh is a kind of high strength, high benefit of reinforced concrete in building material, is the automated production line in the factory, will have the same or different diameter of the longitudinal and transverse reinforcement, respectively, to a certain distance between the vertical arrangement, all the intersection in resistance spot welding of steel fabric together, is a large-scale production in the factory, to replace artificial banding high efficiency new type construction of reinforced steel products.
The diameter of welded wire mesh for cold-drawn round rebar is 4-12mm.
Cold drawn round steel welding network should be CPB550 class cold drawn smooth steel.
Hot rolled ribbed mesh
According to the raw materials can be divided into: cold-rolled ribbed mesh, cold-drawn smooth round mesh, hot-rolled ribbed mesh, of which cold-rolled ribbed mesh is the most widely used.advantages
