The price of a 20x20mm aluminum profile cannot be calculated from its outside dimensions alone. Cost depends on profile weight, alloy, wall thickness, slot design, finish, machining, length and quantity. For a bulk order of 20x20 aluminum profiles, suppliers normally quote by piece, metre or kilogram after reviewing the exact cross-section.
“20x20mm” only describes the overall width and height.
One profile may be a simple square tube. Another may contain four T-slots, internal ribs and a central screw channel. Their metal weight and die complexity will be different.
Before comparing prices, identify whether the required product is:
Solid square bar
Hollow square tube
T-slot industrial profile
LED channel
Architectural trim
Custom extrusion
Quotations for different cross-sections are not directly comparable.
Aluminum extrusion cost is strongly connected to the amount of aluminum in each metre.
The theoretical relationship is:
Profile weight per metre × order length = total profile weight
Wall thickness, internal cavities and slot geometry all affect weight. A lighter profile may reduce material cost but might not provide the required load capacity or screw retention.
Buyers should request the profile’s theoretical or measured unit weight instead of estimating from its outer dimensions.
Different alloys have different material, extrusion and performance characteristics.
The requested alloy should match the intended use. A decorative LED channel and a structural industrial profile do not necessarily need the same mechanical properties.
Temper requirements can also add processing steps. The quotation should state both alloy and temper so that alternative offers are based on comparable material.
Mill-finish aluminum is normally the simplest option. Additional finishes may include:
Anodizing
Powder coating
Brushing
Polishing
Customized colour finishing
Pricing can change with coating type, film thickness, colour, surface-preparation standard and order quantity.
Small batches in a special colour may carry a higher unit cost because the finishing line still requires setup and process control.
A standard extrusion cut to stock length is different from a finished component.
Additional charges may apply for:
Precision cutting
Drilling
Tapping
Milling
Countersinking
Connector preparation
Assembly
Individual protective packing
For a complex finished part, machining time may affect the price more than a small change in aluminum weight.
A bulk order of 20x20 aluminum profiles spreads setup, inspection and packing costs across more pieces.
Standard profiles using existing dies can usually be ordered more economically than a custom 20x20 section requiring new tooling. Custom development may include:
Die charge
Trial extrusion
Sample cutting
Dimensional inspection
Tool correction
Sample approval
The tooling cost should be separated from the production price so buyers can understand repeat-order economics.
Our manufacturing scope includes extrusion, CNC machining, cutting, drilling, surface finishing, assembly and packaging.
This allows buyers to request either raw profile lengths or finished components. It also means the quotation must clearly state which operations are included.
Our industrial aluminum profiles are intended for frames, automation structures, equipment guards and similar modular applications.
Provide the cross-section drawing, alloy, temper, length, finish, machining details, packing and quantity. If no drawing is available, specify whether the product is a square tube, T-slot profile or another section.
