best for: commercial and institutional floors with 120 to 200 mm joints where a blockout is not available and an all-metal surface rated 35 kn is required.

Introducing the OF-1660

The ECOMATE SM Series OF-1660 is an all-aluminum surface-mount floor expansion joint cover for new and renovation projects where a blockout is not available. A surface-mount aluminum frame on one side and an aluminum profile on the other carry a glide plate that bridges the joint and slides as the slabs move. It is 28 mm high, covers joints of 120 to 200 mm and is rated 35 kN, for parking structures, pedestrian bridges and stadium concourses.

movement
01 — movement

thermal movement accommodation

the aluminum glide plate slides within the profile to take thermal movement and settlement of ±25% of the joint width, with no elastomer exposed to traffic.

water barrier

water protection

the optional water barrier below the of-1660 carries water away along the joint, so the structure below stays dry as the joint moves.

load bearing

rated 35 kn in the system drawings for heavy pedestrian and light vehicular traffic, the all-metal surface suits car parks, pedestrian bridges and stadium concourses.

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
