ASTM A615 Concrete Rebar Grade 40

A615 grade 40 steel adds the most benefit when building materials must hold concrete in compression. Strength is one of the differentiators for these two rebar grades. The minimum tensile strength for A615 grade 40 steel is 70.05 ksi. It has a minimum yield strength of 40 ksi.

ASTM A615 Reinforcement Bar Grade 75

Unlike the former two kinds, ASTM A615 is a deformed steel standard categorized under American standards. These are generally available in diameter between 9.5 mm and 43 mm, and length between 6 m and 12 m. Generally, the steel bars that fall under this standard are under deformed or plain carbon steel. The grades that fall within this standard are Grade 40, Grade 60, Grade 75, and Grade 80.

Epoxy Resin Coated Steel Bar

Epoxy resin coated steel bar is an epoxy resin protective coating prepared on the surface of ordinary steel bar by electrostatic spraying powder high temperature sintering process. The coating has excellent chemical corrosion resistance and does not react with acid and alkali. And the coating has anti-permeability, so it can delay the corrosion medium (such as water, oxygen, chloride, etc.) contact with the steel, so that its corrosion resistance life is greatly extended. China's epoxy coated steel bars adopt national standards GB/T 25826-2010 and Ministry of Housing and Construction standard JG/T 502-2016 (replacing JG 3042-1997). American standards are ASTM A775/A775M and ASTM A934/A934M, and British standard is BS ISO 14654.

HPB300/HRB335/HRB400/HRB500 Reinforcement

B1499.2-2007 is a European standard steel bar. Generally, GB1499.2-2007 standard deformed steel bars are made using the hot-rolled method, meaning that these are the most common types of deformed steel bars. These are available in different lengths and sizes, all the way from 6 mm in diameter to 50 mm in diameter. When it comes to length, 9 m and 12 m are the common sizes.
