Saint-Gobain Gyproc Gypframe Starter Channel, 3000mm 100SC80, Perimeter Track for Ceiling Grid Start

It's a galvanised steel, Z-shaped starter channel designed to provide a solid fixing foundation for plasterboard in dry lining and partitioning. It supports and braces studs and is particularly useful for outside corners and door frames, helping to improve strength and stability of the wall or ceiling system.

Length: 3000 mm. Depth: 70 mm. Width: 70 mm. Material: galvanised steel. Shape: Z-shaped starter channel. Intended for dry lining walls and ceilings and for fixing plasterboard or similar finishing materials.

Position the channel along the planned wall or ceiling line, align with the top track or supporting framework, and fix securely using appropriate screws. It serves as the fixing foundation for plasterer’s starter beads and provides a stable platform for subsequent studs and plasterboard installations. Use a hammer and compatible screws to secure into the framing as you build the partition or lining.

Galvanised steel offers higher strength and superior corrosion resistance compared with aluminium, resulting in a more durable and stable support for plasterboard, especially in partitions and dry lining that may experience mechanical loads or impact.

You’ll typically need a drill or hammer, suitable screws for fixing into the supporting structure, tin snips or metal cutters to trim to length, a level to ensure straight alignment, and optional plasterer’s beads or studs as part of your overall wall system.

Ideal for dry lining walls and ceilings, partitioning, or any gypsum board installation that requires a solid fixing base. It’s also used to prepare outside corners and door frames, and to provide a stable platform for electrical or plumbing runs embedded within the wall.

Designed for interior dry lining, the galvanised steel offers corrosion resistance, but it is best used in interior dry conditions. Avoid prolonged exposure to moisture or water-prone areas unless the system is specifically rated for such use.

There’s also a 100SC90 variant for different load/board requirements: https://fepy.com/product/gyproc-gypframe-3000mm-starter-channel-100sc90. These options let you choose the channel size and compatibility that best fits your project’s plasterboard thickness and stud spacing.

Variants differ mainly in the channel/stud size and recommended plasterboard compatibility. They’re designed to work with different wall assemblies and loading requirements, so choose the size that matches your stud spacing and the plasterboard thickness you’re using in your dry lining system.

Yes. Align the channel carefully along the intended wall line, use a level during installation, fix at regular intervals into the supporting framework, and ensure the channel is square to the wall. When preparing corners or door frames, use appropriate corner supports or beads in conjunction with the channel to maintain rigidity and clean edges.

Yes, it can be cut to length using tin snips or metal cutters. When trimming, ensure clean, straight edges and deburr burrs to avoid injury or interference with plasterboard fitting. Always wear appropriate safety gear when cutting metal.

Yes. The galvanised steel construction provides durable, corrosion-resistant support that enhances the strength and stability of dry lining partitions and ceilings, helping ensure a solid fix for plasterboard and reducing the likelihood of movement or misalignment over time.
