The 100mm Heavy Duty Galvanised C 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 delivers high load‑bearing strength while accounting for standard manufacturing tolerances. Its heavy‑gauge profile provides excellent stability, making it ideal for straight wall sections, boundary installations and soil‑retaining applications. Designed for long‑term durability, this 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.

Common Uses

  1. Retaining walls with 75mm sleepers
  2. Straight wall sections & boundary walls
  3. Landscaping and garden wall construction
  4. Residential & commercial retaining systems
