best for: high seismic zones, airports, hospitals, convention centres, and critical infrastructure requiring large-gap coverage with multi-directional movement capacity.
Introducing the D-4000
The PROFLEX WC Series D-4000 is a centre-bar seismic expansion joint cover for interior and exterior walls and ceilings where thermal, settlement and multi-directional movement is expected. Extruded aluminum support profiles carry a cover plate, a rubber insert and a steel turnbar assembly. The cover plate can be aluminum, bronze or stainless steel, and the profile can be powder coated to match the wall or ceiling finish.

Aesthetic Choice
D 4000 focuses on seamless integration with wall aesthetics. Its ability to be powder coated in any RAL color allows it to match or complement any wall finish, making it an ideal choice for both functional and design-conscious projects.
Low profile Design
Engineered to minimize visual impact while maximizing functionality, the D 4000 integrates smoothly with wall surfaces.
Custom Powder coating
Available in any RAL color, the D 4000 can be perfectly matched to existing wall colors or used as a design element, offering unparalleled aesthetic flexibility.
Water Barrier for External Application
The D4000 model is designed to excel in external applications, offering seamless integration with a water barrier. This innovative feature ensures superior waterproofing, making it the perfect solution for areas where water ingress is a concern. Durable and reliable, the D4000 sets a new standard for protection in challenging environments.
Rubber Gaskets for Noise Dampening
Integrated rubber gaskets provide noise reduction between metal components, minimizing wear due to movement.
Premium Architectural Material
Constructed from high-grade aluminum, offering an optimal balance of strength, flexibility, and weight.
