High grade steel roofing for residential and commercial roofs in New Zealand today includes the top-tier caliber steel products leading the hierarchy of quality in 2018. It is true that brass, copper and stainless steel are higher in the galvanic chain of quality than zinc and aluminium-coated steel frequently used as metal substrates that are pre-painted. However, if these varied types of metals make contact with steel, damaging corrosion may result.
Also, water running or seeping from brass or copper piping or spouts can cause pre-painted metal cladding and roofing to corrode. By using top quality steel products for roofing installations and repairs and protecting this quality steel from other metals of less quality, you can enjoy having a sturdy, attractive and practical steel roof for long-term use.
Types of High Grade New Zealand Steel Roofing for Long-Term Use
Advanced types of top grade New Zealand steel roofing materials for reliable, long-term use as residential or commercial roofing installations and repairs today include the following:
• Zincalume®. – As its name suggests, this strong roofing material it is a zinc/aluminium alloy coated steel that gives a significantly longer service life than a galvanised coating. The materials act in alignment with each other, combining the anti-corrosion safety of aluminium with the strong protective action of zinc. This top grade steel product with a zinc and aluminium alloy outer coating lasts significantly longer than steel with a galvanised top finish.
Protected by its outer shield of zinc and aluminium, Zincalume offers a formidable product with strength and long-prevailing durability. An ideal choice for sturdy roofing, even in coastal areas with airborne salt-water mist, Zincalume will go the distance, providing you with an attractive, contemporary solution for a cost-effective and extremely durable roof.
• COLORSTEEL®. – This popular roofing material is available in a wide array of shapes, sizes, finishes and styles to enhance most roofing projects, which allows builders and roof installers to leave design options open and flexible. This roofing material is easy to install, which can save working crews installation time and property owners, money.
This steel product is commonly available for use in three forms—corrugate, tray and trapezoidal. While the neat and repetitive ridges of corrugate give volume and texture to roofs, trapezoidal profiles give a crisp, definite and bold modern appearance. Streamlined tray profiles offer a pleasing minimalist look and enhanced curb appeal to advanced building architecture.
• Galvanised Steel. – Used to manufacture sheet gauges equaling less than 2 mm., galvanised steel is produced via the metallic coating line and surface-coated with zinc. Hollow objects and piping are also made of this form of steel.
Some products are manufactured of steel and then hot-dipped galvanised for long-term durability. When used for roofing, if another metal comes into contact with the surface of this form of steel, the zinc coating will corrode while the underlying steel maintains its original quality.

When installing commercial and industrial gutter systems, it is extremely important to use optimal quality steel materials to avoid any subsequent corrosion and surface staining, streaking or general discolouration. By using top caliber steel, you can also help prevent surface denting or rippling under pressure.
Steel is very strong and can withstand more pressure and wear-and-tear than many other metals used as building materials. Quality steel is also quite durable and will not be worn down or weakened by the elements and the effects of severe storms that bring harsh weather conditions. The best quality steel today is also biodegradable and is categorized as an eco-friendly building material.
Important Aspects of Using Quality Steel Materials for Commercial and Industrial Gutter Systems
Some important aspects of using quality steel materials for commercial and industrial gutter systems include the following:
• Avoid Mixing Steel Products During Installation or Repairs. – It is important to avoid mixing different steel products during gutter installation and repair services. For example, galvanised steel is somewhat less durable than Zincalume® or Colorbond®. For this reason, these products should not be combined for gutter system installations or repairs because they will not age and deteriorate at the same rate.
Also, if different brands of prepainted steel are used to complete a gutter system installation for a building, their surfaces can look identical at the time of installation. However, within just a short period of time, differences in colour, surface gloss and surface weathering many become obvious, marring the appearance of the gutter system.
• Use Quality Colorbond or COLORSTEEL® to Help Prevent Swarf Staining. – Swarf is a term used for steel debris that results from cutting or piercing steel roofing or cladding surfaces with drills or friction saws. Some steel workers refer to discarded steel items like nails, screws, nuts and rivet shanks as swarf as well.
When this debris comes into contact with steel surfaces, it can cause rust-like stains and corrosion on these surfaces. Although quality prepainted steel like COLORSTEEL® and Zincalume® may escape the effects of swarf that is scattered on these steel surfaces during nearby installation or repairs to roofing areas, gutter systems made of lesser quality galvanised or non-coated steel may have swarf staining, which is often stubborn and difficult to remove.
• Select Top-Tier Steel to Help Avoid Gutter Denting or Surface Scratching. – By choosing top quality steel gutter systems with prepainted or precoated surfaces for installation on commercial or industrial buildings, you can help prevent denting, bending or scraping of gutter system parts during product shipment to the building site and throughout installation procedures.
Because denting can impede full flowing capacity of water through and out of gutter systems, and serious surface scratching can weaken steel surface resistance to early signs of deterioration, even very minor damage to gutter system parts should be carefully avoided.
