Trims and Perimeters Overview

• The precise alignment between sections
• Easy installation
• Exterior quality polyester powder finish as standard
• Custom-made extrusions available

Finishes

• Products are extruded from aluminium alloy
• Products are normally supplied with an electrostatically applied polyester powder finish to exterior quality BS6496
• Tested to achieve a 1000 hour salt spray test performance
• The standard colour is RAL9010 20% gloss, alternative colours can be selected from the BS and RAL ranges Special finishes are also available on request:
• SAS FT (Fine-textured)
• SAS AB (Anti-bacterial)
• Anodised in all colours
• Polished and chemically brightened in either silver, gold, copper and brass
• High porosity primer is available for dry lining profiles to provide greater adhesion for conventional drywall jointing and finishing compounds

Suspended Ceiling Applications

Perimeter Trims

The SAS extensive range of perimeter trims is designed to accommodate all types of suspended ceiling systems by masking the edges of tiles at both the perimeters and penetration points. Shadowgap style perimeter trims provide an additional attractive feature detail. Channel trims are generally used for masking the cut edges of metal ceiling tiles. Wedges hold the tile edge tightly in place to give a clean finish. Threaded trims are designed to match the thread-form details of Alugrid-Q and are used on full tile perimeter details. Angle trims are designed for Trucell, mineral fibre and GRG ceiling tile systems.

Column Rings and Radiused Trims

Perimeter trims and shadowgap sections can be rolled to form radiused profiles and circular column rings to match perimeter details. Rectangular column trims can be supplied prefabricated for easy on-site installation. These are normally supplied in two parts. A list of trims that are suitable for rolling or highlighted on pages 116-117. When specifying or ordering radiused trims it is necessary to state whether they are required toe-in or toe-out, further details are available on page 133.

Plasterboard Perimeters

A plasterboard margin can provide an attractive feature to a suspended ceiling and minimises the need for cut tiles. This solution is particularly effective for irregular perimeters, corridors and small cellular spaces with existing structural walls. Important: Plasterboard should be independently supported for margin widths over 450mm. The range of tile to plasterboard trims is designed to accommodate all ceiling types with a choice of shadowgap options. A number of trims feature tapered fins that permit the use of conventional tape and joint finishes to achieve a smooth interface with the plasterboard. A range of plasterboard perimeter trims and shadowgaps provide appropriate matching details between the plasterboard and the wall.

Plasterboard Bulkhead/Change of Ceiling Level

Plasterboard upstand trims can be used to create low cost bulkhead and changes in ceiling level features. The appropriate perimeter trim or shadowgap should be used to support and mask the edge of the higher level ceiling tiles or plasterboard.

Metal Tile Bulkheads & Change of Ceiling Level

Metal bulkheads can be constructed using aluminium extrusions and standard metal tiles. Vertical bulkhead sections are available to create an attractive feature: a change in ceiling level or an interface with another building element. By using standard products, these extrusions offer a high quality low cost solution that is ideal for modest budgets or smaller projects where special fabrication is not feasible.

Partition Head Fixing to Threaded Tee Sections

A number of tee sections incorporate a continuous M6 threadform to provide a fixing point and give lateral restraint to partition systems. This threadform can also be used for fixing lightweight signs and fixtures.
