FAQs

Yes we do double glazing in our W40 and W50 TB suites which can accommodate for a minimum of 22mm IGU.

All our steel products are manufactured in New Zealand.

Yes you can! You don’t have to be an interior designer or an architect to buy steel windows and doors. Just make sure you have an installer or builder present to install your frames. If you don’t have an installer or builder, contact us on 09 377 3888 or email enquiry@steelwindowsanddoors.co.nz to find out how we can help.

External units are restricted to certain sizes for example if the wind zones are above very high. A majority of our units are under 2.7m x 1.2m per sash, however we can accommodate for larger sizes, please contact us for any larger units. Internal units generally don't have the same restrictions.

We regularly make hinged, pivot, sliding and bifold doors as well as side hung, awning and sliding windows.

Generally, the more complex the design, for example more glazing bars (mullions) means more labour in welding and materials etc therefore the more panes (lights) the more expensive the unit.

Depends on how far along the process you are. If you are editing them before manufacturing and fabrication begins then we may be able to edit them. Bear in mind there may be an additional charge if we have to recreate shop drawings based on your revised project details.

Yes you can do so when sending us your request or when getting a quote.

We are located at 55 Angle Street, Onehunga, Auckland.

The price of steel joinery is significantly more than aluminium because of the labour content involved, each joint needs to be welded and sanded and finished manually by hand whereas aluminium is often just screwed and glued together. Additionally, because of the bespoke nature of the profiles they are rarely available and are costly to make.

Yes, we do make units for delivery nationwide from Northland to Otago.

We are currently in the process of getting a suite ready for fire testing.

Steel is stronger than aluminium and less likely to deform or bend under weight, force or heat- making it resistant to different types of weather conditions.

We can accommodate for a wide variety of single glazed glass, safety glass where it is required by regulations. So that includes toughened, laminated, decorative such as broad reeded or other types. In double glazing we can do any type of combination that you would normally see in other types of joinery such as low E and argon filled if required.

See the process of how steel is rolled here.

Our frames have full RAL availability, meaning if you’re after a specific colour- we can source it. Browse our extended colour range or send us a message if you can’t find the colour you’re after.

If you’re not sure about colours, our experts are always on standby to help with any recommendations you are after.

All our steel windows and doors include glass provided by trusted local glaziers.

We offer installation services for small jobs, talk to us to see whether we can help. We work with trusted glaziers who provide a full range of glazing options.

The cost of steel joinery comes from the process as a whole, the materials are imported and cannot be made here, then the labour content is 2-3 times higher than aluminium and obviously because steel is a ferrous metal the corrosion protection process is far more extensive with usually a 4 stage process to protect the carbon steel from rusting.

Yes, steel joinery can be used in coastal areas, our units go through a rigorous 4 stage corrosion protection process in order to prevent any rust. Obviously, like anything, it won’t last as long in a harsh coastal environment compared to an inland, low wind zone area so will require more maintenance just like your cladding and roofing that are also exposed to the salt water.

Depending on what suite you are going for, the profiles range from 22mm - 50mm with the W20 being the slimmest and the W50 TB being the largest.

We have a selection of options that we use regularly but until the job hardware is specified, we cannot quote on it. All standard items such as hinges, rollers and tracks are included.

All our steel products are designed to stand the test of time and backed by a 15-year durability warranty. For more information about our warranty, check out our terms and conditions.

General cleaning:

Precautions:
- Never mix solvents or cleaning solutions.
- Use help if working with a large window or door panel to avoid injuries.
- Wear appropriate safety gear.
- Immediately clean spills.
- If using an alcohol cleaner, test a small area first to avoid product damage.

Coastal Care:
For coastal homes near salt water, we recommend a quarterly inspection and clean. Salt and other abrasive substances must not be allowed to build up over time.

Our lead times vary depending on the workload and time of year. Please call us to get a more accurate timeframe but generally it is 12–18 weeks from approval of your final drawings (when manufacturing starts), depending on job size and unit types.Timing depends on international shipping of materials.

Yes we do! We ship worldwide — talk to us about freight to your location.

Shop drawings are estimated at the time of the quote depending on the job it can be a couple of hours of work to a week if it is a complicated job.

The freight is calculated based on the delivery address and can vary depending on the size of the units but it is always at cost we don’t mark up the freight.
