Corner (L) Channels 100mm

The 100mm Heavy Duty Galvanised Corner Channel is a strong, structural steel section used to build retaining walls with 75mm or 80mm concrete or timber sleepers. Manufactured from galvanised steel with a 6mm nominal thickness, it provides exceptional load‑bearing strength while accounting for standard manufacturing tolerances. This heavy‑gauge L‑shaped channel - also commonly referred to as a corner post in retaining wall construction - supports sleepers on two adjoining sides, making it ideal for 90‑degree turns, boundary corners and soil‑retaining applications where maximum stability is required. Designed for long‑term durability, the channel resists corrosion and performs reliably in both residential and commercial retaining systems. Available in a full range of lengths to suit small garden walls through to large structural retaining projects.
