Company Profile In Southern Africa Hulamin Extrusions are the leaders in The aluminium extrusion business of Hulamin Extrusions was developing extrusions for a diverse range of markets which founded 40 years ago by Alcan. design products and solutions using the benefits of extruded aluminium. Today Hulett Extrusions have production plants in Olifantsfontein, Pietermaritzburg and a sales office in Cape Quality from Start to Finish Town.

Shipping tolerances Extruded products will, within practical limits, be supplied in the number of pieces ordered. Unless otherwise stated, orders for production by Hulamin Extrusions will be subject to a mass or piece quantity tolerance of ± 10%. If over-shipment is not permissible the order shall be endorsed “Do not over-ship mass” (or “Pieces” as is applicable) in which case an under-shipment of 10% may be supplied. Supply of an exact number of pieces or other shipping tolerances closer than those stated will be subject to enquiry, and may incur a price premium. Other requirements Orders should be clearly detailed with any special requirements. Minimum acceptable quantities per item The process is such that a minimum length of extrusion emerges from the extrusion cycle. This results in certain minimum quantities being readily produced. All enquiries will be handled by our sales offices who will advise on minimum quantities. A price premium is applied to smaller orders. Masses The masses shown for sections in this catalogue are for guidance and may vary slightly according to the alloy and the dimensional accuracy achieved when produced and within the permissible tolerances. = = 5 April 2015 Hulamin Extrusions Standard Profile Catalogue The Properties of Aluminium Aluminium has a unique and unbeatable combination of pro- Corrosion resistance perties that make it a versatile, highly usable and an attractive A thin layer of oxide is formed when exposed to air.
