Skyrange’s process starts at the very beginning with high quality drawings produced in AutoCAD since 1990.
Detailed shop drawings help customize the product and boost the accuracy of the fit. Drawing content includes hardware items and fixings with precise proportions. Two experienced personnel are dedicated full time to the task.
Preparation and manufacture
Skyrange rescued original equipment and tooling from traditional Australian steel window manufacturers. The preservation of superior steel window manufacturing equipment gives us the foundation for our manufacturing process today. We have also restored or rebuilt some of the original tooling and equipment to safeguard the high standards of beauty and workmanship our clients enjoyed in the 20th century.
As a result, we’ve maintained the processes for shaping, cutting, and piercing that were essential for consistency in the past. We have also broadened our scope for material preparation with computer numerically controlled (CNC) milling, plus additional drilling, cutting, and folding equipment.
Steel window manufacturing from the early and mid 20th century was based on a mass production ideology. We have focused on custom manufacturing with each item undergoing individual assembly and testing. It promotes accountability and flexibility in maintaining the bespoke steel window environment that prevailed from the 1980s onwards.
Assembly
Highly experienced personnel have dedicated, ergonomically designed, and fully equipped work stations,. We assemble and test all items individually. The personal attention of each staff member imparts a sense of ownership and achievement in the workplace.
Finishing
Completed and tested items have all hardware removed in preparation for hot dip galvanizing or blast and prime painting.
All galvanised items require careful and accurate straightening. We use. a special purpose hydraulic straightening table designed and built at Skyrange. It ensures no compromise to the surface of the profiles or the galvanised coating. We then refit all hardware to the doors and windows prior to despatch. Door handles, if supplied are boxed separately.
Ex-works finishes
Hot dip galvanizing provides the best protection for steel doors and windows. The process involves immersing the product in molten zinc. Zinc gives overall protection, especially to areas never seen again after installation.
Our prime paint process involves in-house grit blasting and spray application of Dulux Metalshield primer. We provide the choice of dark grey or black Metalshield primer.
A galvanised finish gives superior protection. However, it can obscure some of the finer points of our workmanship due to zinc build up over welded areas and some light textural coating over all surfaces. Windows and doors often remain in their galvanised finish without any top coats (except in high corrosion environments.)
Prime paint highlights smooth joints and surfaces, and the quality of the workmanship is much more evident. Prime paint looks better but can’t be guaranteed to coat all hidden surfaces. It is a protective coating for the steel but it is not UV resistant.
We recommended you treat prime painted steel windows and doors with a paint top coat.
