Datasheet JOINTEC GM - GML PRODUCT DESCRIPTION JOINTEC GM profiles are modular expansion joints that can be adapted to various heights. They are composed of aluminum, brass or stainless steel modules available in three different sizes that stack upon twin aluminum anchoring flanges. A central, synthetic rubber insert joins the two sides of the profile. Designed to bear loads of large scale buildings or building compounds, they can be installed in the interstitial space between two sections of a building or between two bays. This technical joint links these interspaces, moving horizontally and vertically to accommodate a building’s structural and material settlement. The structural bays defined by this profile should be further subdivided with smaller scale movement / expansion joints, chosen according to the expected use and flooring type.

positive profile MATERIAL DESCRIPTIONStainless Steel + Aluminum Base + Resinprene Insert Steel profiles are made by cold forming sheets of constant thickness, thus differing from the corresponding aluminum and brass versions made by hot extrusion, while maintaining their application and dimensional characteristics. Stainless steel effectively resists high mechanical stress and is particularly suitable for use in the chemical, food, and hospital sectors, where hygiene, durability, and chemical resistance are essential. Normally produced with a semi-gloss finish, a brushed finish can also be achieved...

positive profile MATERIAL DESCRIPTIONAluminum + Resinprene Insert The primary aluminum alloy EN AW-6060 in T6 temper is suitable for complex extrusions, offering high strength and an excellent natural surface finish that lends itself well to subsequent finishing processes. RESINPRENE Vulcanized rubber: Resinprene vulcanized rubber is a modified compound based on EPDM and NEOPRENE whose particular characteristics we highlight: Optimal mechanical properties in an operating temperature range from -40 °C to + 150 °C Resistance to aqueous fluids, oils, and hydrocarbons. Low permanent deformation in...

APPLICATION 1. Choose the profile according to the loads and expansion to which it will be subjected. If necessary, level the subfloor using a layer of plastic mortar with a width of 10 cm approx. Calculating in advance that when the laying is completed the joint will be perfectly flush with the finished floor; 2. Spread the adhesive in the profile application area with the help of a notched trowel; 3. Cut the profile to the required length; 4. Align the joint, checking that it is perfectly linear. If present, fix the wings to the substrate using mechanical or chemical expansion plugs sized according...

CLEANING AND MAINTENANCE STAINLESS STEEL: Stainless steel is easy to clean and very hygienic because of its smooth, nonporous surface, which hinders the growth of bacteria. To keep it in good condition, simply wash it with warm soapy water, rinse it thoroughly and dry it with a soft cloth. If exposed to weathering, periodic cleaning is recommended to prevent corrosion. Brushed surfaces should be cleaned in the direction of brushing. In case of scratches, a specific polish can be used with a soft cloth. Avoid cleaning agents containing hydrochloric acid, hydrofluoric acid or bleach, as well as...
