HDG cable tray means Hot-Dip Galvanized cable tray.

After the steel cable tray has been manufactured and assem bled, the entire tray is immersed in a bath of molten zinc, resulting in a coating of all surfaces, as well as all edges, holes and welds.

Coating thickness is determined by the length of time each part is immersed in the bath and the speed of removal.

Hot dip galvanizing after fabrication creates a much thicker coating than the pre-galvanized and electro-galvanized process, a minimum of 3.0 ounces per square foot of steel or 1.50 ounces per square foot on each side of the sheet (according to ASTMA123, grade 65).

The process is recommended for cable tray used in most outdoor environments and many harsh industrial environment applications. 

Hot Dip Galvanized Steel: Straight sections and fittings shall be made from 14 gauge structural quality steel meeting the minimum mechanical properties of ASTM A1011 SS, Grade 33 and shall be hot-dip galvanized after fabrication in accordance with ASTM A123.

All hot dip galvanized after fabrication cable trays must be returned to point of manufacture after coating for inspection, conditioning and labeling. 

Hot Dip Galvanized Steel - All siderails and rungs shall be made from steel conforming to the requirements of A1008/A1008M-07,SS grade 33, type 2 or A1011/A1011-06b SS, grade 33 and shall be hot dip galvanized after manufacture per ASTM A123 providing a minimum thickness of 1.50 oz per ft. 

Products which are either Hot Dip Galvanized (HDG) after manufacture, stainless steel or non-metallic can be stored outside without cover (excluding boxed items). When stored outside products should be stacked in a method that ensures adequate drainage.

However outside storage is not recommended for galvanized products due to wet storage stain. Ideally, all metallic products should be stored undercover in a dry, unheated environment and be loosely stacked off the ground to ensure adequate ventilation. It is important that products that have different finishes are kept apart. 

Hot-Dip Galvanized After Fabrication is recommended for prolonged outdoor exposure and will usually protect steel for 20 years or more in most atmospheric environments and in many industrial environments. For best results, a zinc rich paint (available from B-Line) should be applied to field cuts. The zinc rich paint will provide immediate protection for these areas and eliminate the short time period for galvanic action to “heal” the damaged coating.
