Architectural Fins Manufacturer in India
Extruded aluminium vertical and horizontal fins — engineered for wind load and deflection, finished for the life you specify.
KBG Group manufactures extruded aluminium architectural fins in India — vertical blades, horizontal shading fins and feature profiles, with the brackets and carrier system engineered alongside them. A fin is a cantilever in the wind before it is a design feature, and that is where the engineering effort goes.
Manufactured in Mumbai and supplied across Delhi-NCR, Bengaluru, Chennai, Pune, Hyderabad, Ahmedabad and pan-India — plus the GCC.
Architectural fins by application
Fins do three jobs at once: they shade glazing, they give a facade depth and rhythm, and they have to stand up in the wind at the top of a tall building. The bracket is usually the hard part.
Commercial towers
Full-height vertical blades carried on a secondary steel or aluminium frame.
Metro stations
Feature fins over concourse glazing, with access and maintenance designed in.
Airport terminals
Long horizontal shading runs across large spans of curtain wall.
Institutional buildings
Solar shading sized to the orientation and the glazing specification.
Hotels & residences
Balcony and window fins where appearance and water run-off both matter.
Retrofit facades
Fins added to an existing building, where the fixing substrate governs.
Why specify KBG architectural fins
Length, depth and spacing set the appearance; wind load decides whether the design is buildable. We calculate the pressure on the fin for the site's basic wind speed and terrain category to IS 875 (Part 3), then size the extrusion, the span between brackets and the bracket itself to carry it within a deflection limit that keeps the line of the facade straight.
Slender fins can also move in a way that is structurally safe and still unacceptable — visible vibration, or noise at a particular wind speed — so span and fixing stiffness are checked, not just strength. Profiles are extruded to IS 1285, and finishes are specified by exposure: an architectural powder coat to a standard such as AAMA 2605 for the most demanding, or anodising where a metallic finish is wanted.

Architectural Fins Manufacturer in India — FAQs
Common questions from consultants, EPC contractors and procurement teams.
What decides the size of an architectural fin?
Appearance sets the starting point and wind load decides whether it can be built that way. Once the depth and spacing are chosen for the look and the shading, the pressure on the fin is calculated for the site's basic wind speed and terrain to IS 875 (Part 3), and the extrusion, bracket spacing and bracket are sized to carry it within an agreed deflection limit. On a tall building that calculation often sends the design back a step.
Can fins vibrate or make noise in the wind?
A slender fin can move visibly, or hum at a particular wind speed, while remaining perfectly safe structurally. It is a stiffness and fixing question rather than a strength one, so we check span, section stiffness and bracket restraint as well as the load case. It is far cheaper to resolve on paper than on a finished facade.
Powder coating or anodising?
Powder coating gives a far wider colour range and, in a high-performance architectural specification such as AAMA 2605, very good colour and gloss retention. Anodising gives a metallic finish integral to the aluminium, with different wear behaviour and a narrower palette. Coastal and high-UV exposure should push the specification up rather than down, whichever route is chosen.
Do fins actually reduce heat gain?
Yes, where the geometry suits the orientation — horizontal fins work on southern exposures and vertical blades on east and west, because the sun angle differs. The useful figure is the shading the fins give over the hours that matter for that facade, worked out with the glazing specification rather than claimed for the fins alone.
Can fins be added to an existing building?
Often, and the deciding factor is what they can be fixed back to. The existing structure, the substrate condition and the access available usually govern the design more than the fin profile does, so a retrofit starts with a survey of the fixing zone. Loads still have to be carried back to something that can take them.
