High Adherence Reinforcing Strips
The reinforcing strips used by The Reinforced Earth Company are S355JR steel strips with a minimum ultimate tensile strength (UTS) of 510N/mm2, complying with the requirements of BS EN 10025. Hot-dip galvanized to BS EN ISO 1461. The strips have a ribbed profile which enhances the adherence of the strip when placed within a compacted granular fill. The apparent coefficient of friction m*, between the fill and the strip is usually estimated from the current BBA Certificate No. 99/R106.
Taking account of the sacrificial thickness, the manufacturing tolerances and partial safety factors, the design strength of each strip type is:
  50mm x 4mm (HA)      37.1kN (main body)                   25.9kN (connection)
  45mm x 5mm (HAR)   46.7kN (main body)                   46.7kN (connection)
These design capacities are referred to in the Roads & Bridges Agrément Certificate No.99/R106, issued by the BBA for structures designed to BD70/03.

Steel Tie Strips
The tie strips used by The Reinforced Earth Company are S355JR steel lugs with a minimum ultimate tensile strength (UTS) of 510N/mm2, complying with the requirements of BS EN 10025. Hot-dip galvanized to BS EN ISO 1461.
