best for: high seismic zones, airports, and critical infrastructure requiring enhanced seismic floor joint coverage.

Introducing the Z-4100a

The PROFLOOR RM Series Z-4100A is a spring-centered seismic floor expansion joint cover for high seismic zones, covering joints of 40 mm to 200 mm with 60 kN to 90 kN load capacity. Recessed aluminum frames carry an aluminum or stainless steel center plate that compression-spring centering bars return to center after movement; optional PTFE tape lowers the sliding friction. Profile heights are 38 mm and 50 mm; the ZK-4100A variant closes the joint against a wall.

Clip-in water barrier

TPE (Thermoplastic Elastomer), the advanced material used in the clip-in water membrane, combines the flexibility of rubber with the strength of thermoplastics. This unique blend enables exceptional waterproofing performance and durability, with resistance to weathering, UV radiation, and chemicals. TPE’s flexibility allows for easy installation and adaptability, while its heat-welding capability ensures watertight seals. Utilizing TPE, the clip-in water membrane offers a reliable solution for preventing water damage in expansion joint systems across diverse applications.

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.
