Steel products have various use in buildings. High-quality building with high resistance and lower weight needs high-quality material to construct.

Here at STC, we collect all steel products that uses in construction.

Rebars:

Rebar is  One of the most material in the building. The parameters that matter about this product are tensile, elongation, weight and plasticity. In terms of their quality, ribbed rabers have different grades like A2(340), A3(420), A4(520) and… that they have a difference in strength and appearance.

STC gather all of this grades with guaranteed quality and reasonable price.

Here is a mechanical test of A3.

Tensile strength(Re MPa) Yield strength(Rm MPa) elongation
478 640 22%

A4(520):

ASTM A4 rebar is another grade of ribbed bars. By its high tech producing method, A4 have better mechanical properties. Using this grade worth a lot because it reduces the rebar using up to 30%.

Here is a mechanical test of A4.

Tensile strength(Re MPa) Yield strength(Rm MPa) elongation
526 664 20%
