Finishes

Electro-Plated Zinc (ASTM B633)

Electro-Plated Zinc (ASTM B633)

This process deposits a coating of zinc on the steel or iron by electrolysis from a bath of zinc salts.  This coating is pure zinc and adheres to the steel or iron with a molecular bond.  A maximum of .5 mills of zinc can be applied using this method.

Epoxy Coating

Epoxy Coating

The COPPER-GARD finish offers a high degree of corrosion resistance.  This finish is for copper tubing installations.  It provides superior corrosion protection and insulates against dissimilar metal contact, thus preventing electrolysis.  The process applies a baked-on epoxy paint to steel stampings and iron castings.  In the three-step process, the parts are zinc plated to .0002" thick, an epoxy copper colored powder is then applied by an electrostatic method, and finally, the coated parts are baked at 180 degrees for 20 minutes.

Our BLACK EPOXY is a Polyester coating that is extremely durable, provides superior chemical, abrasion and weathering resistance, furnishes excellent protection against UV rays, very good corrosion resistance and is environmentally friendly.

PVC Coating

PVC Coating

Vinyl coating of the metal prevents galvanic reaction between dissimilar metals, provides corrosion resistance, reduces noise, and can be used where glass or plastic pipe contact with metal is not desired.

Pre-Galvanized Zinc (ASTM A653)

Pre-Galvanized Zinc (ASTM A653)

This coating is also referred to as “mill galvanized” or “hot-dip mill galvanized”.  This process continuously rolls steel coils or sheets through molten zinc.  The steel is then cut or slit to size.  Cut edges are not zinc coated, however, zinc near the uncoated steel becomes a sacrificial anode, which protects the bare areas after a short period of time.

Hot Dipped Galvanized

Hot-Dip Galvanized (ASTM 123)

This coating provides superior corrosion resistance to that of electro-plating.  The process calls for the steel or iron product to be completely immersed into a bath of molten zinc, which creates a metallurgical bond.  The minimum coating thickness is 1.5 ounces per square foot per side (3 ounces per square foot of steel or iron).  Caution should be taken when specifying Hot-Dip Galvanizing on certain products.  Products with threaded components should either have the threads protected from the galvanizing process or chase the threads subsequent to hot-dipping.  Products with critical size tolerances should account for the thickness of the coating.

Zinc Magnesium

Zinc Magnesium (Zn-Mg)

(E35 Magnelis® Zinc Aluminium Magnesium Coating) 

This material is ideal for use in construction and civil engineering applications where good corrosion resistance in aggressive environments is required. Magnelis® is a flat carbon steel product coated on both sides with a zinc-aluminium-magnesium alloy. This alloy, composed of 93.5% zinc, 3.5% aluminium and 3% magnesium, is applied by means of a continuous hot dip galvanizing process. Thanks to its 3% magnesium content, Magnelis® offers self-healing on cut edges and superior corrosion resistance in chloride and ammonia atmospheres. This optimum chemical composition has been selected to provide excellent results in terms of corrosion resistance and will withstand a minimum 600 hours of salt spray testing making it as good, if not better, than hot dipped galvanized.
