GB 70# Hot Rolling Spring Steel Wire Rod With Light Round Surface
Description:
For producing hot coil helical springis It is also mainly used for
a variety of concrete structure reinforcement, such as large
bridges, crane beams, cement poles, prestressed concrete pressure
pipe, multi-factory frameworks.
Category:
Can be pre-stressed wire diameter, the intensity level, the surface
coating or cross-section morphological classification:
1. according to diameter and can be categorized as: 4mm, 4.8mm,
5.0mm, 5.1mm, 6.0mm, 6.35mm, 7.0mm, 7.8mm, 8.0mm, 9.0mm, 10.0mm,
11mm, 12mm and so on.
2. according to intensity level can be classified as: 1470MPa,
1570MPa, 1670MPa, 1770MPa and 1860MPa so.
3. in accordance with the surface coating can be classified as: no
coating prestressed steel wire, prestressed epoxy coated steel wire
and galvanized prestressed steel wire.
4. in accordance with the surface morphology can be classified as:
light round prestressed steel wire, spiral rib (spiral ribbed or
helix grooved) prestressed steel wire, the pressure wave (crimped)
prestressed steel wire or nicks (indented) prestressed steel wire
and so on.
5. in accordance with treatment process can be categorized as
follows: cold-drawn prestressing steel wire (no slack performance
requirements) and low relaxation prestressed steel wire.
