Introducing the OF-1685

The SUPERMATE SM Series OF-1685 is a heavy-duty surface-mount interlocking floor expansion joint cover for heavy pedestrian and vehicular traffic. A surface-mount aluminum frame carries two interlocking aluminum profiles with an EPDM insert, fixed with anchor bolts at 300 mm on center. Only 19 mm high with a 240 mm sightline on a 100 mm joint, it is rated 35 kN for warehouses and parking garages.

movement
01 — movement

thermal movement accommodation

the interlocking aluminum profiles take horizontal thermal movement and settlement of ±25% of the joint width, plus some vertical movement, and neither profile can lift under wheel load.

water barrier

water protection

the optional water barrier below the of-1685 carries water away along the joint, so the structure below stays dry as the joint moves.

Optional Vapor Barrier

For added protection, an optional vapor barrier is available, constructed from either EPDM or TPV, which offers high tensile and tear resistance, ensuring long-term performance against moisture penetration

Premium Aluminum for Architectural Materials

Aluminum grade 6063, the premium material used in the expansion joint cover, offers strength, corrosion resistance, and durability. Available in T5 and T6 tempers or customized to meet project needs, this versatile alloy ensures exceptional structural integrity and longevity. Aluminum 6063 withstands high-traffic areas, extreme temperatures, and corrosive conditions, making it an ideal choice for diverse applications, from commercial facilities to infrastructure projects
