Alumatic Recessed Heavy Duty

For internal applications requiring a heavy duty recessed aluminium cover -

Triple sealed recessed aluminium access covers. Aluminium or brass edging strips are 8mm deep, which allows horizontal edges to be ground and polished in-situ up to 6mm. High quality floor finish up to a depth of 38mm of tile, carpet, blocks or terrazzo can be accommodated. Our products in this range are available as singles, single duct runs and as beamed multiple units.

 

MATERIAL
Aluminium alloy 6063 and 6082 for low corrosion and brass or aluminium edging for superior finish.

DESIGN
The Alumatic® has a number of unique features designed to improve
appearance and performance. The section is vertical, featuring a greater cover clearance for increased ease and frequency of use. Mechanical joints for structural strength and improved aesthetic appearance and welded reinforcing bars need no adjustment on site. Base plates, lock and lift facility, and two seals are fitted as standard.

LOCKING
Lock and lift bosses in either brass or aluminium, depending upon edging finish, are fitted as standard (stainless steel bolts fitted as standard).

SEALS
The primary (top) dirt seal and secondary fitted seals offer protection against the ingress of dirt and fluids. The tertiary (inner) grease seal is an integral part of the unit and may be utilised to give a complete gas,air and water-tight seal.

DUCT RUNS AND BEAMED MULTIPLES
The Alumatic ® is also available to suit all sizes and configurations.
