ZINCALUME® steel and galvanised products have very similar working characteristics. Since they are materials that are industrial in nature, it is important to be aware of their few characteristics. Below are some helpful information regarding Zincalume steel.


At the cut edge, ZINCALUME® steel provides similar protection to galvanised coatings. The zinc or aluminium alloy coating of ZINCALUME® steel provides galvanic protection to bare steel exposed at cut edges and by deep scratches.

Surface Passivation

Surface passivation enhances the protection of the galvanised and ZINCALUME® steel product during storage, forming, handling and fixing. It largely eliminates the need for rollforming oils, offers improved wet stack corrosion resistance and generally makes the product more mark resistant during handling and fixing.

Handling and Storage

The normal storage care, site cleanliness and installation procedures used for GALVSTEEL® products apply to ZINCALUME® steel products. Although passivation provides improved protection during storage, care should still be taken. If ZINCALUME® steel becomes wet during storage, the product should be immediately separated, wiped with a clean cloth and placed in a position where it can completely air dry.  


As with GALVSTEEL®, ZINCALUME® steel is suitable for all but the most severe forming operations. With ZINCALUME® steel, the passivation system acts as a dry lubricant and in most cases will eliminate the need for additional lubrication in most forming operations. Solvent-based lubricants must not be used.


ZINCALUME® steel can be satisfactorily welded using the following techniques: GMA (Gas Metal-Arc, often called MIG), Resistance welding (spot or seam) and MMA (Manual Metal-Arc). When welding ZINCALUME® steel, excessive weld currents must be avoided. With correct welding procedures, sufficient coating is normally left on the ZINCALUME® steel sheet to protect the substrate from corrosion. Weld repair should be carried out by coating with a zinc-rich paint. Adequate ventilation must be provided even though the welding of ZINCALUME® steel gives off fewer fumes than galvanised steel.

Joining and Sealing

ZINCALUME® steel cannot be soldered. Join ZINCALUME® steel in the same way as recommended for COLORSTEEL® prepainted steel products. Use a neutral cure silicone sealant in conjunction with mechanical fasteners such as blind rivets. Care should be exercised in the choice of rivets. Aluminium rivets are recommended. Monel, stainless steel and carbon steel rivets must not be used.


Most fasteners complying with the corrosion requirements of Australian Standard AS3566 “Screws – Self-drilling for the building and construction industry” are suitable for use with ZINCALUME® steel. Stainless steel fasteners should not be used with ZINCALUME® steel or COLORSTEEL® prepainted steel products in any environment. Aside from that, lead headed nails must not be used and you should use only low carbon (< 15%) non–conductive sealing washers.

Metal roofs can also lower energy bills by reflecting unwanted heat in the summer and increasing insulation during colder months. Plus, finishing a metal roof with a durable coating allows for an even wider variety of colours, textures, and design options.

Commercial and residential roofing, while serving the same ultimate purpose, have their respective differences. These differences are essential to know which one is the right option for you. Peruse the following differences between commercial and residential roofing and know which one is fitted to your needs and preferences.

Commercial and Residential Roofing Structural Needs

The structural needs of a commercial roof are different from a residential roof. Obviously, commercial roofs may be considerably larger – imagine the size of a roof on a shopping mall compared to the size of the roof on your house and you’ll get the picture. In addition, the load requirements, fixtures, and even materials will vary significantly between commercial and residential roofs. For example, commercial roofs must have a larger load-bearing capacity than residential roofs often just because of the materials involved in their construction. Similarly, installation of a commercial roof requires a much larger crew than residential roofs simply because it’s a bigger job.

Commercial and Residential Roofing Functions

With respect to the function of the roof, commercial roofs tend to have more protrusions than residential roofs. While a residential roof may need to accommodate chimneys, skylights, and a few other protrusions, commercial projects must also consider ventilation systems, smokestacks, pipes, roof entrances, and mechanical needs. Likewise, there are specialized construction specifications for commercial and residential roofs. For example, commercial roofing materials are often chosen based on the function of the commercial building; if the commercial building features heavy machinery, the roofing material must be able to withstand heat discharge. On the other hand, residential roofs are generally constructed with respect to the homeowner’s personal preferences regarding appearance, durability, and maintenance.

Commercial and Residential Roofing Project Scope

Whereas commercial roofers must consider the function of the commercial building and the unique specifications that affect the roof’s construction, residential professionals must be informed about the particular needs of their clients. Obviously, both types of roofs must be constructed to withstand the climate of the region, but residential types tend to be constructed with an eye for aesthetic and commercial roofs with a mind on functionality.

Commercial and Residential Roofing Needs

Most importantly, because of the differences between the two types, you will find contractors have different needs as well. Commercial roofing is generally considered a much more involved if not difficult job and finding skilled laborers for the work may contribute to the cost of projects. The fact that these projects tend to be considerably larger than residential projects also means that commercial crews are larger, and many residential contractors cannot accommodate the manpower needed to complete a commercial job.

Today, the average cost of replacing a roof can be considered as an expense that lies way over the budget. For such a costly investment, you need to make sure that you choose the right contractor as well as materials for your reroofing project. Aside from that, there are so much more to keep in mind so as not to render your project obsolete and dysfunctional. Below are items to consider before proceeding to your reroofing project.

Inquire about Reroofing Project’s Proposed New Ventilation

Proper ventilation has a huge impact on your roof’s longevity. Improving your roof’s ventilation helps regulate the attics temperatures during the summer and minimises moisture accumulation in the winter. Ask your contractor whether they will include such features as gable and ridge vents.

Ensure that your Reroofing Project Maximises Energy Efficiency

An energy-efficient roof helps lower your energy bills as your air conditioning unit does not have to work exceptionally hard to cool your home. Cool roofs are normally made of materials that do not easily absorb the sun’s heat. Apart from keeping your home’s interior comfortable, this also reduces the roof’s maintenance costs. While in the past such roofs were mostly made of bright colours, dark hues are now becoming available.

Consider Installing Low Maintenance Gutters for your Reroofing Project

Misaligned and unsightly gutters will probably not augur well with your new roof. Choose a roofing company that provides low-maintenance and preferably, seamless gutters. Choose gutters that are not held in place by gable overhangs or eaves as these are susceptible to water damage.

Consider Installing an Airtight Chimney Cap for your Reroofing Project

Although chimney caps are quite inexpensive, they are often overlooked. A chimney cap reduces the energy consumption in your home by preventing heat from escaping and keeping snow, sleet or rain from getting into your home. It also prevents animals such as raccoons, squirrels, birds, mice, and rats from accessing your home.

Prevent Ice Dam Formation by Installing Eave Flashings for your Reroofing Project

Eave flashings are your roof’s unsung heroes. This is a thin weather-proofing material which, alongside your roof’s underlayment, prevents moisture from getting to the shingles. Eave flashings also prevent the formation of ice dams.
