3) Standards & Tolerances
- • ASTM B221 (extruded bars, rods, wire, profiles) and EN 755-2/-9 (mechanical properties & tolerances)
- • GB/T 6892 (China) for extruded profiles
- • Straightness, twist, leg length, thickness and corner radius per order standard and die class
4) Weight per Meter (Quick Reference)
Formula (mm): kg/m = 0.0027 × t × (A + B − t), where A and B are leg sizes and t is thickness.
| Size (A×B×t, mm) | Calculated kg/m | Note |
|---|---|---|
| 25×25×3 | 0.381 | Equal leg, light duty |
| 40×40×4 | 0.821 | General fabrication |
| 50×50×5 | 1.283 | Structural frames |
| 60×40×6 | 1.523 | Unequal leg |
| 75×75×6 | 2.333 | Heavier duty |
Weights are theoretical; confirm with MTC for each lot.

6061 vs 6063 — Quick Selection Guide
6061-T6 (Structural)
- • Higher strength & good machinability
- • Excellent weldability; re-heat treat if critical strength in HAZ
- • Common for trailers, frames, fixtures, machine bases
6063-T5/T6 (Architectural)
- • Smoother surface, tighter cosmetic control
- • Best anodizing response (clear/black/bronze)
- • Ideal for trims, glazing, displays and interiors
FAQs
1) 6061 vs 6063 — which should I choose?
Choose 6061-T6 for strength-critical frames and trailers; choose 6063-T5/T6 for architectural looks and anodizing quality.
2) Can you supply unequal angles?
Yes—e.g., 60×40×6, 75×50×5, 100×50×6. Share your list and we’ll match die availability or run custom.
3) Are corners sharp or rounded?
6063 architectural angles are typically sharper; 6061 structural angles may have a slight outside radius and tapered legs depending on the die.
4) What lengths do you stock?
Common stock is 6.0/6.1 m. We cut to any length and offer precision 45° mitered corners for frames.
5) What finishes are available?
Mill, clear/black/bronze anodized (8–25 μm), powder coated (RAL), brushed; protective film for cosmetics.
6) Can you pre-drill and deburr?
Yes—CNC drilling/slotting, countersinks, tapping, plus deburr and kit packing with labels.
7) What standards/tolerances apply?
ASTM B221 / EN 755-2 (mechanical) / EN 755-9 (tolerances). Straightness, twist, leg length, thickness per standard and die class.
8) How do I pick thickness for a span?
Provide span, load and support spacing—we’ll run a quick check and recommend an angle size/grade and finish.
9) What is the MOQ and lead time?
Stock sizes ship fast; custom sizes/finishes are typically 2–4 weeks. MOQ depends on size and finish—often 500–1000 kg per spec.
10) Do you provide test certificates?
Yes—EN 10204 3.1 MTC with chemistry and mechanicals; anodize/powder coating certificates upon request.
