When it comes to achieving a seamless flush door finish, not all door jamb systems are created equal.
Over the years, the Ezy Jamb by EZConcept has become well known amongst architects and builders alike. However, as the market evolves, Altro’s Euro Jamb sets a new benchmark in both strength and longevity. Unlike folded steel jambs, our 1.8mm extruded aluminium profile delivers superior rigidity, precision, and resistance to cracking compared to Ezy Jamb’s 1.2mm steel – even in high-traffic or coastal environments.

| Corrosion Resistance | Aluminium is naturally non-ferrous and therefore rust-proof. When anodised and painted, it is extremely resistant to corrosion – ideal for wet areas and coastal environments. | Steel contains iron, which naturally rusts when exposed to moisture. The Zincanneal-coated steel used in some steel flush jamb systems (e.g., 1.2 mm zinc/iron-alloy coated steel) provides corrosion resistance through its coating. However, like all coated steels, if the coating is damaged, not fully sealed or compromised, the underlying steel substrate is at risk of corrosion. ** |
| Profile / Rigidity | The Euro Jamb’s 1.8 mm extruded aluminium profile features internal rectangular webbing and multi-chamber geometry, forming a closed structural section. This design provides exceptional rigidity and resistance to twisting – the same engineering principle that makes box beams and hollow structural sections stronger and more stable than open or folded shapes. | The 1.2 mm folded steel profile, formed from a single sheet, lacks the multi-chamber geometry of an extruded aluminium profile, which is engineered with internal webbing and channels. Because profile cross-section geometry drives rigidity more than raw material strength alone, the folded steel system may offer less resistance to torsional or bending movement compared with a purpose-designed aluminium extrusion. *** |
| Paintability | Anodised and pretreated surface offers excellent paint adhesion in accordance with AS/NZS 2311:2009 | A60 Zincanneal finish is designed for paint adhesion in accordance with AS/NZS 2311:2009. * |
Steel jambs have served the industry well, but as building standards and expectations rise, so must the products. The Altro Euro Jamb is the smarter, stronger choice – a flush aluminium jamb engineered to stay true, resist cracking, and maintain a seamless finish for decades. It’s not just an alternative to EzyJamb – it’s a new benchmark for modern architectural detail.
