About Us

Delta Roofing and Manufacturing Ltd has been based in Hamilton for over 50 years. In that period Delta have manufactured and installed specialist roofing products made from various substrates:

• Colorsteel  
• Copper
• Stainless Steel  
• PVC  
• Rubber

 
 Delta has manufactured and installed colour steel downpipes for 20 years. Our costings showed 40% of the end price was in the joins.

 We have patented in New Zealand and Australia, a unique method of bending aluminium tube.

 Around the bends we keep the thickness on the outside of the bend virtually equal to that on the inside of the bend with thinner tube, yet significantly stronger than material used in other pipes.

 We launched this technology onto the market in 2009 and have secured a large share of the group housing market. (see gallery)

 In this website we are making our product available to all potential retail customers and architects.

 This technology will dominate pipe technology for housing in all aspects over the next three years.
