Rechteckrohre
Material
AlMgSi0.5 F22
(EN AW 6060 T 66)
Available surfaces**
Bright chrome plated
Stainless steel colored anodized
Natural color anodized (E6EV1)
Other surfaces on request.
*) Due to manufacturing reasons, it is possible that there may be slight deviations with the maximum length of 6,000 mm.
ATTENTION: For small quantities up to 500 kg, for anodized surfaces, the maximum length is 5,030 mm due to manufacturing reasons.
**) Due to production reasons, it is possible that there is no surface coating on the contact surfaces at the ends of the profiles (up to 80 mm)
Lengths up to 6,000 mm*
Rectangular tubes
The aluminum rectangular tube profiles are delivered in standard stock quality. What does that mean?
Standard stock quality means that the raw material or the raw aluminum rectangular tube profile according to the following. Standards:
EN 573-3
Chemical composition and product forms
EN 755-2
Mechanical properties
EN 755-1
Technical terms of delivery
EN 755-3/-4/-5/-9
Profiles, tolerances on dimensions and form
The above-mentioned standards regulate the tolerances of the limit dimensions, alloy components, properties and delivery conditions of a material.
When refining aluminum rectangular tube profiles, the limit dimensions and the alloy components are of particular importance. The limit dimensions not only describe the external dimensions of the aluminum rectangular tube profile with the tolerance dimensions but also the maximum tolerable roughness depth of the aluminum rectangular tube profile. (Press structure, press groove depth, waviness, …)
Refined aluminum rectangular tube profiles in standard stock quality always have visible ripples and press structures, which cannot be removed for production reasons.
Reason: The standard storage quality is originally only designed for technical applications.
The alloy components provide information about which substances are in the aluminum rectangular tube -Profile can be pressed together. Aluminum rectangular tube profiles in standard stock quality can contain alloy components that are disruptive to the finishing process and lead to small surface defects such as specks, small holes or dark stripes. The above-mentioned material-related appearances do not justify a complaint, as we cannot influence this. However, experience shows that these “surface characteristics” As a rule, they remain undetected because they are hardly visible visually.
Beyond this, better surfaces can only be achieved with specially manufactured aluminum rectangular tube profiles, whereby the purity and surface quality are then taken into account. t of the raw material can be better limited and can therefore also produce an even better final surface. However, a minimum pressing quantity of 500 kg and, if necessary, the purchase of a special tool for production are required.
