  • These are essentially pure aluminium with a minimum 99% aluminium content by weight.

  • Alloyed with manganese (Mn) as the main alloying element. Alloy 3003 is alloyed with additional copper (Cu), Alloy 3105 and Alloy 3005 with magnesium (Mg).

  • Magnesium (Mg) is the alloying element, and therefore offers superb corrosion resistance

  • Alclad is composed of a core layer of 3000 series aluminium, clad on both sides with an aluminium 7072 series layer, which acts as an anode over the entire surface, hence preventing pitting corrosion and prolonging the life of your investments. It is available in Alclad 3003 and Alclad 3004.

Austenitic (T304 and T316) Stainless Steel Jacketing

Stainless Steel Type 304 or 316 Jacketing with Polykraft Moisture Barrier

Stainless Steel Type 304 or 316 Jacketing with Polysurlyn® Moisture Barrier

Steel Type 304 or 316 Jacketing

Austenitic (T304 and T316) Stainless Steel Jacketing is the material of choice when corrosion resistance and fire protection are required. Usually furnished in a 2B finish

  • Austenitic stainless steel alloyed with nickel and chromium

  • It has essentially the same material make-up as Type 304, but with the addition of molybdenum. This addition increases corrosion resistance, particularly against chlorides and industrial solvents. In saline environments, the use of T316 is recommended due to this addition.

    Field experience, test and theory provide evidence that a moisture barrier on stainless steel jacketing contributes to preventing galvanic corrosion of steel piping and equipment.

Aluminium Zinc Coated Steel (Aluzinc®/Galvalume®)

Aluminium Zinc Coated Steel 185 g/m2

ZX Profiled Aluminium Zinc Coated Steel 185 g/m2

This is a flat carbon steel product coated on both sides with an aluminium-zinc alloy. The coating is composed of 55% aluminium, 43.4% zinc and 1.6% silicon and applied by means of a continuous hot dip galvanizing process. It exhibits superior corrosion resistance when compared to hot dip zinc coated steel.

Aluminized Steel

Aluminized Steel Type 2 to ASTM A463

ASTM A463 describes two types of aluminized steel. Aluminized Steel Type 1 is a flat carbon steel coated with an aluminium-silicon metallic layer. Aluminized Steel Type 2 incorporates a layer of commercially pure aluminium.

  • Coating comprises of an aluminium-silicon layer containing 5 to 11% silicone. Intended for use in heat resistant applications. Exhibits poor corrosion resistance in neutral salt spray tests when compared to Type 2, especially in the silicone phase in an aluminium surrounding. Typically coil coated on both sides to improve emissivity and corrosion resistance.

  • Coating comprises a commercially pure aluminium. A coating weight of 300 grams per square meter, including both sides is industry standard (T2M-300)

Corrugated and profiled sheets

Acoustics

Our range of heavy layers are designed to add mass to a spring-mass system.

Phonisol BM series are composed of polymers filled with naturally occurring minerals, mainly barium sulfate and calcium carbonate. Phonisol BM0050 contains no lead, unrefined oils or bitumen. All mineral fillers are naturally occurring ground powders which are chemically unaltered from the state at which they were originally mined. Sound Reduction Index (R) have been tested against EN ISO 10140-2:2010.

Vibraflex is a heavy, flexible thermoplastic self-adhesive bitumen material that can be adhered to the inside face of sheet metal and serves as an anti-drumming material. It is strong in insulating low frequencies in combination with sheet metal enclosures.

Tapes, Foils, Sealants and Adhesives

For vapor protection purposes we offer a wide variety of foils, tapes and sealants.

Whether the functionality is

• to waterproof metallic jacketing with sealants (in cartridge of pre-formed),
• to wrap a piping system with (pure aluminum or stainless steel) foil,
• to provide a secondary vapor barrier,
• to seal the overlaps of primary vapor barriers,
• to adhere insulation materials to each other,
• to make a contraction or expansion joint,

this product category provides a wide range of products.

Primary Vapor Barriers for Cold Insulation

Preventing the ingress of water and water vapor is paramount to a well-designed cold insulation system. If moisture or water vapor is allowed to enter a cold insulation system, it will freeze and mechanically destroy the insulant itself.

The large vapor pressure acting on a cold insulation system requires a flawless vapor barrier that is easy to install.

INSU-W-RAPID BV has been the pioneer in this field. Our IWR701® range of butyl based vapor barriers was introduced in 1999 and ended an era of vapor barrier coatings that were difficult to install and had a limited shelf life.

Membrane XT is a bitumen-based primary vapor that complements our butyl range of vapor barriers, and is predominantly installed on cellular glass.

Stainless Steel Banding, Seals and Tools

It is manufactured by means of rotary shearing, also referred to as coil slitting. In order to obtain a safety edge, banding can be deburred.

We can manufacture stainless steel banding to customer specification in terms of alloy (T304 or T316), surface finish, thickness, width, roll weight and length. Custom-made solutions with special packaging – such as our boxed banding – are available on request.

Wing type seals are used whereby the banding is folded around the seals. Crimp/closed type seals are notched utilizing special tools to keep the banding in place.

A variety of strapping tensioners and notching tools is available.

Banding and seals are not only manufactured in stainless steels, materials such as aluminum, galvanized steel and exotic alloys can also be provided.

As a result of temperature change bands can be exposed either to excessive tension (expansion of equipment as a result of higher temperature) or to loss of tension (equipment contraction). In those cases, the use of permanent tension devices such as breather springs and compression springs should be specified. The use of banding with an integral spring system – expand-R-band – can be considered as an alternative.

Wire Mesh, Expanded and Perforated Metals

Welded wire mesh is predominantly used as a fencing material in personnel protection applications, whereby a structure is built around an object that is potentially dangerous.

In the selection of the proper material for your system, a variety of material specifications can be chosen.

For welded wire mesh, specify material grade, wire diameter, mesh size, roll length or panel size.

Metals can be perforated using a staggered round perforation (RT) or holes at 90° angles (RU), as well square holes at 90° angles (CU). All metals can be perforated. Each perforation pattern has it’s own percentage of open area, depending on your requirements. It can be supplied in sheets or in rolls.

Hexagonal wire mesh is available in stainless steel and galvanized steel, in various mesh sizes and wire diameters.

Screws, Rivets and Mattress Hooks

To secure metallic jacketing in hot insulation applications we provide a wide variety of screws and blind rivets in a large number of grades and specifications.

Where screws need to comply with the requirements of DIN7981, DIN7971 or DIN7976, we have a suitable product available in various grades (carbon steel, stainless steel).

Blind rivets are stocked in a large number of grades – aluminum, stainless steel, galvanized carbon steel – and a large number of sizes.

Mattrass hooks are used to secure non-rigid insulation wired matts.

Toggle Latches and Spring Constructions

To enable the removal of metallic jacketing, toggle latches and hooks are available in various functionalities, sizes and material grades. Whether self-locking, adjustable, push-pull, quick release in carbon steel or stainless steel, we have them available.

Popular toggle and latches include our IWR828, IWR802 and IWR803. Request our various Product Data Sheets for more details.

To keep metallic jacketing in place where the insulated surface expands or contracts, spring constructions are used to ensure constant tension on the metallic band. Breather spring, compression spring and super compression springs; we have them available ex stock.
