South Atlantic Reinforcing
South Atlantic Reinforcing specializes in corrosion resistant rebar and sells Hot Dip Galvanized reinforcing bar (rebar) and Hot Dip Galvanized welded wire mats (mesh) to both domestic US and export markets. As a premiere supplier to both bar fabricators and the precast concrete industry, South Atlantic maintains an inventory of standard rebar and mesh sizes already galvanized and ready for immediate shipment. Our HDG rebar is processed to conform with ASTM A767 Standard Specification for Zinc-Coated (Galvanized) Steel Bars for Concrete Reinforcement* and can be provided as either Type 1 or Type 2 bar*, and our HDG welded wire mats conform to both ASTM 123 Standard Specification for Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products and ASTM 1060 Standard Specification for Zinc-Coated (Galvanized) Steel Welded Wire Reinforcement, Plain and Deformed, for Concrete.* All of our products are produced domestically and are qualified under 'Buy American' contract plans. When it comes to hot dip galvanized reinforcing, trust South Atlantic to be your supplier.
Hot dip galvanized reinforcing has been successfully used for decades to protect concrete in high risk areas from damage caused by the corrosion of embedded reinforcing steel, and many engineers and specifiers are choosing hot pip galvanized coatings for reinforcing used in structures at high risk from corrosion attack such as marine and coastal construction, bridge decks subjected to de-icing salts, industrial settings and other harsh environments where the use of corrosion resistant reinforcing (CRR) is advisable.
Autopsy data from periodic inspections of concrete bridges poured using galvanized reinforcing in the early 1970s* show that the coating weights on the bars are still in excess of the originally specified minimums, a clear indication that Hot Dip Galvanized reinforcing is a system worthy of consideration for engineers seeking structure life at or above 100 years or more. In fact, hot dip galvanized reinforcing was the corrosion protection chosen by the designers of the massive The Baha'i Temple at Qutub Minar near Delhi in the 1980s, which has an anticipated design life of 200 years.
Hot Dip Galvanized coatings are extremely tough and damage resistant, making then an excellent alternative to epoxy coatings when the potential for damage to the epoxy is a concern or where extended UV exposure is unavoidable. Because HDG is UV stable, it can to be stored outside and uncovered at the job site for extended periods of time with no damage. Also, reinforcing that has been Hot Dip Galvanized can be handled in the same manner as conventional A615 or A706 uncoated bar, with no need to employ special slings and pads. Hot Dip Galvanized reinforcing can also be installed at the jobsite in the same manner as 'black' bar, eliminating special placing sequences and worries about damage to already installed product.
The cost of galvanized coatings on reinforcing will generally add a premium of 25% to 50%to the cost of conventional black bar, similar to the cost of epoxy coating and far less than dual coated or stainless rebar. This premium generally translates into a cost that is less than 1% of total project cost, yet has tremendous potential to reduce future maintenance costs and extend total project life. As Life-Cycle Analysis becomes a larger part of both the Green Construction Initiative and LEEDs calculations, the use of a product shown to extend longevity, is composed of 95%+ post consumer recycled material and is itself 100% recyclable will be a smart choice.
