“Details about 140 exposed frame curtain walls that engineers won’t tell you”
In the logistics center project in the heart of the Dubai desert, the general contractor once questioned: “How can the exposed frame curtain wall withstand the sandstorm?”
We directly placed the test sample of the Visible Frame Series in the wind outlet – three years later, when the sealant of those hidden frame curtain walls cracked, our Industrial Aluminium Profile frame did not even fade the oxide film.
Let’s look at a set of counterintuitive data first
The visible surface has a narrow edge of 6.5mm, but the wall thickness of the profile is 3.0mm (0.2mm thicker than some hidden frame systems)
A 0.03mm steel foil can be stuffed into the frame joints, which is considered unqualified
The flow rate of the drainage trough is 2.8L/s, which is 40% faster than the conventional design
Behind this is the manufacturing iron law of Aluminium Profiles For Curtain Wall:
The melting furnace temperature must be controlled at 665℃±5℃ (the grain will coarsen if the temperature is 1℃ higher)
The extrusion die must be repaired every 50 tons (comparable peers generally use 200 tons)
The end face cutting must be done with a diamond tool (ordinary blades will have burrs)
The truth at the installation site
The Singapore team has made a comparison: when installing our Visible Frame Series, the level in the worker’s waist bag is basically not used – because the profile pre-processing accuracy reaches ±0.3mm, and it is naturally vertical when hoisted in place. On the contrary, the traditional exposed frame system always has to carry a crowbar and a gasket to level it everywhere.
Fatal points that are easily overlooked
Most buyers only care about the thickness of the profile, but they don’t know:
The difference in the width of the insulation strip is 2mm, and the energy consumption may increase by 15% in five years
If the anodized film is lower than 15μm, white spots will appear in the seaside project in three years
The corners of the drainage trough are not rounded, and the blockage rate in five years has increased by 80%
So we insist:
The insulation strip must be 26mm wide (the industry mostly uses 24mm)
The thickness of the oxide film sticks to the bottom line of 18μm
The R angle of the inner wall of the drainage trough ≥1.5mm
The truth about cost
The contractor in Kuala Lumpur has calculated the accounts:
The pre-drilling design saves 37% of the on-site drilling time
Modular packaging reduces the shipping volume by 20%
But the mold cost is 30% higher than that of peers (this is the hidden price of good profiles)
Now there is a rule for accepting urgent orders: Do you want to inspect the goods? Directly connect the workshop via video to see if the pressure curve of the extruder is as smooth as a straight line, see if the temperature record of the aging furnace fluctuates by ±3℃, and see if the quality inspector really uses a micrometer to measure each section
Want a sample? We will cut you a 30cm section of profile, attach a metallographic test report and the melting furnace number. Only those who dare to do this are the manufacturers who really regard Industrial Aluminium Profile as their lifeblood.

Aluminium Profiles For Curtain Wall – Visible Frame Series
Visible Frame Series aluminum curtain wall profile (Visible Frame Series) is a curtain wall system with exposed structure. Through the combination of aluminum alloy frame and glass, metal plate and other panels, it forms an architectural exterior wall with both functional and aesthetic performance. Its frame design emphasizes line sense and geometric tension, which is suitable for commercial complexes, office buildings and public facilities that pursue modern industrial style or need to highlight the structural logic of the building.
