The PKB40S Polyurethane Beam Strap is a 40 mm wide joint connector designed to conceal seams between ceiling beams, rafters, or decorative profiles, delivering seamless architectural continuity. Engineered specifically for rustic interior design, it hides beam joints while replicating the aesthetic of wrought iron metal clamps across wood textures. It imparts a refined, professional finish to ceiling lines in both residential and commercial projects.
Manufactured from high-density rigid polyurethane (150-220 kg/m³), this durable component measures 990 mm in length, 40 mm in width, and 2 mm in thickness. Its thin, flexible profile allows it to wrap smoothly around beam surfaces. Featuring a closed-cell structure, its water absorption rate remains under 1%. Additionally, it maintains dimensional stability without shrinking or warping across a temperature range of -100 °C to +80 °C.
The surface texture features detailed accents inspired by traditional hand-forged iron and leather strap designs. Delivered with a factory-applied primer, the surface is fully prepared for painting prior to installation. It can be finished in black, antique copper, aged brass, or dark wood tones to seamlessly match your design scheme. Significantly lighter than real plaster or metal hardware, it places no structural load on ceilings or walls.
This versatile strap is suitable for ceiling beam joints in living rooms, rafter installations in hotel and restaurant interiors, and decorative residential ceiling trims. When finished with a UV-resistant coating, it can also be safely installed in exterior applications, such as porch beams and eaves soffits.
For installation, ensure the application surface is clean and dry. Apply polyurethane (PU) construction adhesive to the back of the strap, position it over the joint, and mechanically fix it using screws. Fill screw heads and joints with suitable putty, sand smooth using 180-220 grit sandpaper, and complete with an optional primer followed by two topcoats of paint.
