Supplier Selection Questions

What is the difference between hot-dip and pre-galvanized pipe?

Hot-dip (HDG) pipe is galvanized after forming with typical coating weights of 300-500 g/m2 for long outdoor life; pre-galvanized pipe is formed from pre-coated strip with lighter coatings for interior and light-duty use. Both are supplied with MTC.

Can galvanized pipe be supplied with SASO SABER documentation for Saudi projects?

Yes - shipments to Saudi Arabia are supported with SABER / SASO certification, and for other Gulf destinations we prepare the required country-specific import documents on request.

Which sizes do you normally keep in stock for quick dispatch?

Common sizes from 1/2 inch to 4 inch in SCH40, plus selected SCH80, are regularly stocked, so mixed containers can be dispatched within 7-10 days of order confirmation.
