PLANDECON COMBO JOINT

Material Specification

ALLOY RAIL

Alloy Rail is made from high grade of 6061 – T6, which is a proven strength of structural alloys that statistics the requirements of a number of specifications. In extruded shapes, it is treated as an equal alternative to other metal and has long history in furniture, handrails, transportation, industrial equipment, general structure and bridge expansion joint system.

Alloy Rail is a proven and excellent resistance to atmosphere, fresh waters, soils condition, seawater and good corrosion resistance in structural application.

Chemical Composition

Alloy 6061 is a heat-treatable aluminium-magnesium-silicon alloy

FLEXI CRETE

Flexi Crete is a flexible compound system comprising of epoxy / rubberized base mixed with a proportion of graded aggregate. It’s specially formulated and modified compound system not only bonds strongly to concrete, but also asphalt, steel, and many other materials to provide a tough, flexible, waterproof and chemical resistant surface. It’s widely used as in-situ nosing or transition strip for a wide range of bridge expansion joints, especially for PLANDECON COMBO JOINT.

Feature

Simple and easy application
Level can be adjusted during application
Very good adhesive to concrete, asphalt and metal with adequate priming
Good all round chemical and water resistant
Excellent overall flexibility from 10 C to 70 C
Smoother and quieter ride at all speeds
Passable to traffic within few hours after the mortar is laid
Complete waterproofing for bridge joint’s nosing and transition strip
No change in properties under extreme temperatures
Non slip finish surface
