Aluminum Composite Panels sold under the brand name Alupex, is developed with the objective of supplying superior quality panels for modern day construction. 


Alupex range of composite panels is manufactured by multi layer extrusion lamination where two skins of non corrosive special grade Aluminum is sandwiched on to non – toxic polyethylene thermoplastic or a fire retardant mineral core. The external skin surface is available in various finishes and colours made from PVDF paint coatings.  Key features of this product include; attractive designs, durability, longevity, smooth surface, high tolerance and easy installation to name a few. Manufactured by Interplast which is a flagship of group Harwal, the company has 15 years of experience in metal coating and extrusion lamination and has a capacity of manufacturing over 3 million sq. meters a year. 



Alupex is manufactured by Interplast Company Limited, a flagship of the Group Harwal and a proud owner of leading brands such as DECODUCT, EDISON & INTERGARD. It was established in the year 1981 and since then Interplast is the market leader in manufacturing innovative products used in the electrical, construction and packaging industries.

INTERPLAST Building Material's division is providing innovative products for the continuously expanding construction industry in the middle east. This division's primary goal is to develop & manufacture quality products required for the modern building architecture.

Having realized that further diversification is needed to fulfill our growth strategy, in the year 2004, Interplast developed full range of Aluminium Composite Panels especially suitable for gulf harsh weather conditions.The ALUPEX product ranges are the next generation solution for all weather conditions. It is a unique and versatile cladding material used in enhancing new trends of modern architecture.

The solid experience of over 15 years in metal coating and extrusion lamination within Group Harwal companies resulted in establishing a state-of-art manufacturing facility at Sharjah, United Arab Emirates to manufacture over 3 million of ACP's. This facility is fully supported by our technical experts based in USA & Europe.

Standard ACP Composition

Alupex - Aluminium Composite Panels are available in various widths & thicknesses depending upon the intended application. The range is further expanded into Fire Retardant and Stone Finish panels in attractive colours and patterns.

Today, Alupex products are available in 13 types of metallic finishes, 19 types of Solid Colours and 6 Stone Patterns as a standard range. In addition ALUPEX panels are also offered in MIRROR and BURSHED METAL finishes to replace conventionally used Stainless Steel and Mild Steel panels in the various cladding applications.

The standard panel widths available are 1000mm, 1250mm and 1500mm where as the lengths offered are from 2400mm up to 6000mm. However for optimum space utilization for exports we recommend panels lengths to be either a combination of 2400 & 3200mm or single length of 5000mm

Our standard product range is offered with a guarantee up to 20 years depending up on the specifications and colour finishes for all-weather-condition from hot & humid of the Middle East to extreme cold & dry weather of other continents.

We can also offer custom colours and specifications depending upon the minimum order quantity of 2000 sq.meter.


Fire Retardant Aluminium Composite Panels manufactured using a non combustible fire retardant mineral core conforming to CLASS 0 (BS 476) fire rating of British Standard certified by European testing laboratories.

This product range is manufactured using a chemically treated Aluminium surfaces to ensure lower oxidation and superior non-corrosive cladding system for high-end architectural requirements in commercial and public buildings.

The external Aluminium surface is coated with 2 and/or 3 coats system in PVDF (Polyvinylidene Di-Fluride or KYNAR) based paint system using special purpose base primer coatings to ensure superior performance under severe and harsh weather conditions for extended periods.

PANEL THICKNESS:   3, 4 & 6mm
STANDARD PANEL WIDTH:  1000, 1250 & 1500mm

A unique and revolutionary STONE finish Aluminium Composite Panels manufactured using latest coil coating technology. The top skin of Aluminium is coated repeatedly to achieve mixed colour patterns of the combination of PVDF, Polyester and Polyurethane paint systems to achieve a naturally look-a-like marble, granite and other stone patterns. The high gloss and consistent colour strengths are maintained by high temperature baking (up to 255 degree Centigrade). An additional topcoat of clear PVDF is used to maintain extended weathering performance for external cladding applications.

These look-alike stone skins are then subjected to conventional high-pressure extrusion lamination process to manufacture ALUPEX-TONE composite panels. There are various Granite and Marble finishes available identical to natural stones with higher strength-to-weight ratio. These panels are the best alternative to conventionally used natural Granite & Marble tiles.

These paints are especially developed to meet the harsh weather conditions of the GULF region and of the other coastal areas having extreme temperatures, high UV exposure and high humidity. The technical support from our European paint manufacturer and our In-house testing facility, ensure that our high quality surface coatings conform to the standards established by ECCA (European Coil Coating Association) and similar bodies under DIN and ASTM.

A fully integrated manufacturing facility with state-of-the-art coil coating facility and In-house testing laboratory is providing quality products designed to meet the harsh weather conditions of the Gulf region.


ALUPEX is manufactured with state-of-the-art technology of multi layer extrusion lamination where two skins of non-corrosive special grade ALUMINIUM metal sheets are bonded on to the non-toxic Polyethylene thermoplastic or a fire retardant mineral core to form a sandwich panel. The external skin surface is available in various finishes and colours made from fluropolymer coating systems processed by our In-house coil coating facility.

An easy-to-peel protective film further protects the external surface. The internal skin surface is supplied with a non-corrosive service coating to further enhance its protection from cement or galvanic corrosion after installation.
