The Most Tested Expansion Joints in the Industry
ALSF

Product Description

The EMS aluminum cover plate selections are designed especially for areas where floor slabs break to allow movement in the structural slab. The EMS cover plate system bridges the joint gap with minimal preparation for maximum protection. All of the EMS cover plate selections are compliant with the standards of ADA.

The ALSF series is made from 6061-T5 or 6063-T6 aluminum alloy extrusions that are secured to the floor with hex head concrete screws drilled into the concrete.

Recommended areas for usage include warehouses, manufacturing facilities, retail spaces, and stock rooms where the finished floor is concrete. Additionally, they are used in architectural applications such as hospitals, airports and shopping malls where the cover plate must provide safe passage over expansion joint voids and must also accent the interior application.

Optional accents such as color anodize, EPDM-looped moisture barriers are available. Contact EMS for pricing.

Features and Benefits

  • Ease of Installation – The layout of the anchor holes along the edge of the extrusion is a simple process. String line a straight edge parallel to the joint opening. Align the extrusion along the string and drill in the concrete Tap-Con screws. Clean out all the dust and debris; align the center plate into position.
  • Tested To ASTM D-1399 – The design was tested in compression, tension and deflection for 500 cycles. No loss of anchors was noted.
  • Seal Meets ADA Dictates – The ALSF-Series profiles are engineered to meet ADA standards for pedestrian concerns.
  • Flat Uniform Closure - This system remains flush during all phases of thermal movement.
