Metal expansion seals - Import export

Expansion joints serve a crucial role in industrial ductwork by facilitating the controlled expansion and contraction of ducts. Their primary function is to accommodate thermal movements within the ductwork system. They mitigate thermally induced stresses by allowing thermal movements in a relatively unrestricted manner. Expansion joints contribute to the overall flexibility and structural integrity of the system which is essential in preventing the build-up of stress that could otherwise lead to damage in equipment, ductwork, and supporting structures.

The KBD Diffusion team listens to its customers and has experience in recommending building equipment and offers you custom-made metal plates. 20 mm thick, they are sized to the size of your formwork panels, whatever their brand: SATECO, OUTINORD, HUSSOR, COSMOS, DEKO ... They are equipped with tightening nuts corresponding to the dimension of your rods. Thanks to their lifting ances, they are easy to crane and move. They can be delivered with an alignment angle fixed to the side of the sheet of your choice to facilitate their alignment. These sheets allow you to quickly cast your expansion joints without wasting cardboard and polystyrene. They make it possible to gain flexibility while maintaining high pouring rates. In addition, thanks to these expansion joint sheets, you can use the concrete of your choice and the pouring technique that best suits your site.

The Ozdekan EX are waterproof expansion joints that allow absorption of the deck movements. These joints are manufactured with rubber elements and restrained to the structure with proper anchor bolts. The reinforcing metal profiles made of steel are completely inserted and vulcanized to the rubber. This process is a total guarantee against corrosion and allows a longer life to the product. The rubber compound, too, has been intentionally formulated to resist the oil, grease, petrol, salt and sand, without besides, suffering premature ageing phenomena due to sun rays, salt and snow. All the joints follow the deformations and movements of the structure (the movement can exist with every skew angle from 0° to 90°) by shear deformation of the rubber elements. Anchor bolts, made of steel and protected with anticorrosion treatments, absorb the elastic reactions and all the other kind of mechanical solicitations. www.ozdekan.com

The Acme T Seal is a fixed length metal seal manufactured in Tin plated steel. The design features a unique double locking action and inspection holes in the lock box which enable the user and security personnel to view the tips of the "T" mechanism within the lock box ensuring the seal has been correctly locked and has not been pre-tampered. This seal cannot be disengaged by intrusion or manipulation, nor can it be dismantled or cut without leaving obvious traces. It can be manufactured in operating lengths of between 10cm to 95cm and is suitable for use in temperatures of -60ºC to 320ºC (-76ºF to 608ºF). Recommended applications Trailers, Tankers, Containers, Rail freight, Refineries, Cash bags, Postbags, Lockers. Material Matt tinplated steel ** Click for more **
