Doogood hold approximately 3,000 tonne of HDG CHS pipe in various diameters and thicknesses. As well as this we are pleased to assist with surface preparation and hot dip galvanising in Melbourne on custom projects, manufactured items and sections that are not stocked in HDG.

We only procure steel from highly vetted mills that adhere to exacting quality requirements and regulations. Our HDG pipe is made from premium steel coil and galvanised with the best zinc available for maximum corrosion and rust resistance.

Due to our meticulous manufacturing, Doogood galvanised steel pipe may be powder coated, bent, and welded without additional pre-treatment procedures, lowering costs and elevating the quality of our HDG products.

Hot dipped galvanised pipes, posts and parts can withstand years of continuous usage and exposure to the elements without losing functionality, structural integrity, or aesthetic appeal.
