1. Increase material strength
The 650.61 doors are made from 25×25 SHS (square hollow section), however the 650.37 shed doors with their 35×35 SHS are stronger and more durable.
2. Power coated addition
The 650.61 is a raw galvanised product, where as the 650.37’s 35×35 tube is now powder coated grey, to match Bluescope sheets. This also helps protect the welds from rusting. Learn more about the benefits of powder-coated steel finishes by visiting the Standards Australia website.
3. Extra hinge
Upgrading your shed or garage door to a 650.37 will mean an additional industrial hinge. This product now has three hinges rather than two as per the 650.61.
4. Door swing range
In comparison with the 650.37, the 650.61 has a pretty limited 100 degree swing. The 650.37 steel clad door has an increased opening swing of 180 degrees for much better access.
5. Doors in stock
We now hold the 650.37 steel clad shed door in stock, with all colours now ready and waiting to be ordered.

Frequently asked questions
Upgrading from a basic shed door improves durability, security, and overall performance in demanding environments.
Entry-level doors may be suitable for light use, but higher-spec PA doors are designed to support frequent access, stronger construction, and better long-term reliability. This makes them more suitable for workshops, commercial sheds, and high-use applications.
Upgraded PA doors typically offer dual skin construction, improved insulation, and stronger hardware compared to entry-level shed doors.
These features are designed to support better structural strength, thermal performance, and resistance to wear. This makes them suitable for external use and more demanding industrial environments.
Upgrading your shed door allows for stronger materials and more advanced locking systems to be integrated.
Higher-spec doors can be configured with heavy-duty locksets, reinforced frames, and anti-burglary features. These upgrades are commonly used in security door applications to better protect tools, equipment, and stored assets.
Yes, upgrading to an insulated shed door is often worthwhile if temperature control or internal comfort is important.
Insulated cores such as EPS or PIR are designed to support improved thermal performance and reduce heat transfer. This is particularly useful for sheds used as workspaces or for storing sensitive materials.
Yes, pre-hung upgraded doors are typically easier and more consistent to install compared to basic door setups.
They are supplied as a complete unit with frame and hardware alignment already set, reducing installation time and potential errors. This makes them suitable for shed upgrades, retrofits, and new builds.
