Canopies, fascias and parapets

Scope of supply

Canopies, fascias and parapets give a PEB its architectural face and protect loading areas from rain and sun. World Steel designs and fabricates them as part of the building so their loads are included in the frame design; see canopies, fascias and parapets for the technical background.

• Cantilever canopies at the eave or below the eave, with tapered built-up rafters or cold-formed purlin members.
• Roof extensions continuing the main roof beyond the sidewall.
• Fascia systems: brackets, girts and panels forming a vertical or sloped face.
• Parapets extending the wall above the roof, with capping and box gutters behind.
• Soffit panels, trims and gutters for canopies.

Options and variants

Canopy members can be tapered I-sections bolted to the columns, or light cold-formed members for short projections. Fascias can use the standard wall profile, a reverse profile, flat panels or composite aluminium panels supplied locally. Wind uplift on a canopy and wind on a parapet are both high, so connections are designed for these local pressures.

Materials and finishes

Structural members follow the primary framing plate grades and paint system; secondary members and panels follow the cladding materials. Soffit liners are usually pre-painted steel in a light colour. Where a canopy is exposed to sea spray or vehicle exhaust, hot-dip galvanizing or a higher ISO 12944 category is recommended.

Compliance by market

Wind, drainage and detailing references

Parapets need back-sheeting and capping on the roof side; fascias that hide gutters need overflows that discharge outward and safe access for cleaning. See canopies, fascias and parapets and roof extensions.

Documentation, packing and quotation

Deliverables include canopy and fascia framing drawings, calculations including local wind and snow drift, cladding and trim details, and erection drawings. Canopy rafters are packed with the primary frames; panels and trims with the cladding.

A quotation can be prepared quickly when the enquiry states the project location and the code to be used. Please send:

1. Canopy location, projection and height.
2. Fascia or parapet height, profile and finish.
3. Any signage, lighting or solar loads on the canopy.
4. Design wind and snow parameters.
