Circle Developments has developed innovative technology that is unique, flexible and highly versatile, which lends itself to a wide range of applications.

The steel sections produced meet critical design stresses such as bending, compression, tensile and torsional. The thickness of the cold-formed steel sections used range from 0.40 mm (25 gauge) to 1.4mm (16 gauge) and these easily meet the structural requirements of a two-storey building.

The most commonly used steel section is the C-section with a flange width of 38 mm and web sizes ranging from 63 mm to 203mm. These can be combined in a number of different ways to achieve the design properties.

Design parameters such as strength, stability, fatigue and brittle fracture are designed to the American Iron and Steel Institute (AISI) "Specifications for the Design of Cold-formed Structural Steel Members" Standard Code of Practice and related technical documentation.

The Frame-Tech System comprises of steel studs, tracks, rafters and trusses as framing components. These vertical and horizontal framing members serve as structural load carrying components and utilise durable and dependable connectors and fasteners through the use of self-drilling screws and powder-actuated fasteners.

External walls are clad with a waterproof membrane, hexagonal wire mesh, ref mesh and a cement-sand plaster and roughcast finish. Internal walls are similarly clad with either gypsum plasterboard on both sides or with steel lath and a cement-sand plaster with a smooth finish.

Roof trusses and rafters are custom-designed through the IT Software and manufactured in-house from the same raw material (galvanized steel coils). Frame-Tech also utilises an in-house roof cladding product known as Frame-Tech Tile, which is manufactured using 0.4 mm (25 gauge) commercial type light gauge steel. Other roof cladding products such as asbestos cement sheets, clay tile, cement tile, chromadek, etc. can easily be used with a Frame-Tech wall structure depending on the client's requirements.
