Custom Stainless Angles for a Hammam Door Frame
The frame of a hammam glass door is a structural element and a visible detail at the same time, held at arm’s length by everyone who walks through it and surrounded by hot, humid air for its whole service life. For a custom designed door of this type the customer needed non-standard stainless steel angles of 26x25x5x3 mm, with two different wall thicknesses in the same section. Montanstahl produced them by laser welding from the customer’s drawing in stainless steel 1.4404, holding twist and straightness below 1 mm per metre and keeping the outer weld radius under 0.5 mm.
Wellness Interiors Are a Corrosive Environment
Hammams and wellness centres demand materials able to withstand constant exposure to humidity, high temperatures, aromatic oils and cleaning agents, a combination that is more aggressive than it first appears, because condensation, heat and chemistry work on the same surfaces continuously rather than in cycles. At the same time the aesthetic finish and the dimensional accuracy carry equal weight, particularly on visible elements such as a glass door frame, where the profile is part of the interior design rather than hidden inside the construction. For this project the customer needed non-standard stainless steel angles for the structural frame of a bespoke hammam door, and the solution had to deliver durability, corrosion resistance and a refined appearance while respecting tight mechanical tolerances. It is the classic brief of architecturally exposed structural steel, concentrated into a very small section.
A Section Judged by the Eye and by the Gauge
Four conditions framed the work, and they pull in different directions. Very tight tolerances were needed to guarantee the fit and the operation of the door frame, since the glass, the seals and the hinges all locate against the angle and a small deviation shows up as a door that does not close cleanly. The visual quality of both the profile surface and the weld seam had to meet premium standards, which is a harder requirement than it sounds, because a seam that would pass unnoticed on a structural member is visible at reading distance on a door frame. The geometry itself is non-standard at 26x25x5x3 mm, with legs of different thickness that no catalogue covers. Finally the environment demanded excellent corrosion resistance, since humidity, heat, oils and cleaning products act together on a component that is expected to look new for years.
Application Context
Montanstahl produced the custom angles by laser welding directly from the customer’s drawing, a route that accommodates two different leg thicknesses in the same profile because the section is built from separate strips rather than formed from one. The bars were held to twist and straightness below 1 mm per metre with a clean surface finish, and the outer weld radius was kept under 0.5 mm, which is what delivers the sharp corner the design depends on, since a generous external radius reads as a soft, rounded edge and loses the crisp line the architect drew. Stainless steel 1.4404, the EN designation of 316L, provides the corrosion resistance the environment requires thanks to its molybdenum content. Sections of this type extend the range of unequal leg angles into fully custom geometries, available with a choice of surface finishes, and further points are covered in the technical Q&A.
