Black Rebars - Low Price with High Quality

Black rebar is a regular uncoated rebar that provide superior cost effectiveness for applications where there is no moisture. Compared with other reinforcing bars with special coating, such as epoxy or anti-rust treatments, black rebar is prone to rust and corrode, but it is the cheapest and the best for the application where epoxy and anti-rust coatings are not needed.

As we know, standards of black rebar products are the main devise factors for the enforced concrete and enforced mansonry concrete. Several international specifications are available in our company.

Sizes:
Diameter:
#2-#11, #14, #18 or 6, 8, 10, 12, 13, 14, 16, 18, 20, 22, 25, 28, 32, 36, 40, 50mm more details.
Length:
straight: 6-15meters, U-shaped or rounded coils as standards.

Standards:

ASTM A615: Deformed and plain carbon-steel bars for concrete reinforcement This kind of rebar can strength and hold the concrete, and be widely used in low-stress and less-demanding applications. Stress and weight can be absorbed by the rebar, meanwhile, expansion or contraction of the reinforced concrete caused by exposure to heat or cold can be distributed.

ASTM A706: Low-alloy steel deformed and plain bars for concrete reinforcement The ASTM A706 black rebar products, which are molded in open hearths, electric or basic oxygen furnaces, feature their weldable characteristic.it is widely used in bent caps, joints, footings, over sized shafts and so on.

ASTM A1035: Standard Specification for Deformed and Plain, Low-carbon, Chromium, Steel Bars for Concrete Reinforcement.

This kind of rebar is one of the strongest, multipurpose and durable rebar among all of the rebars. It features its anti-corrosion characteristic which makes it suitable to used in applications where involving humid or volatile environments.

Other standards we also can supply, such as:
BS4449, GB(HRB335/HRB400/HRB500), CSA G30.18-M92(R2002), DIN, JIS, SANS, NF, etc.
