What a solar frame drawing must define.
A frame is not a catalogue item, every parameter follows the module design. This is the checklist a frame drawing has to answer before any serious quotation can come back.
1 · Profile geometry
Long-side and short-side profiles are usually different sections. The drawing must fix: profile height and width for each side, wall thicknesses, the glass-groove width and depth (matched to the laminate build-up), the mounting flange, and any internal ribs. If the module is glass-glass, say so, groove geometry and clamping assumptions change.
2 · Alloy & temper
6063-T5 is the common basis for module frames; 6063-T6 or 6005-T6 appear where the design asks for more strength. State the alloy and temper on the drawing, "aluminium" is not a specification, and temper changes both mechanical values and extrusion cost.
3 · Surface & anodising
Colour (silver, black, other), anodising film thickness with its tolerance, and the gloss/appearance requirement if any. If a protective film is required for handling, specify it, including where it must be removable without residue.
4 · Processing
Every hole, slot and punch with position and tolerance: mounting holes, grounding marks or holes, drainage holes and their positions, corner cut-outs. Grounding and drainage are the two most commonly under-specified items, and the two most annoying to discover missing on site.
5 · Corner keys
If the frame assembles with corner keys: key geometry or reference, material, fit requirement, and whether keys ship installed or separate. Corner strength expectations belong in writing, with the test basis stated.
6 · Tolerances & packing
Cut-length tolerance, angle tolerance at 45° or 90° ends, straightness. Then packing: interleave, bundle sizes, carton or pallet format, and labelling, the difference between profiles that arrive install-ready and profiles that arrive scratched.
- Profile sections (long & short side) fully dimensioned, with wall thicknesses
- Alloy & temper stated (e.g. 6063-T5 / T6 · 6005-T6 where specified)
- Anodising colour + film thickness + tolerance · protective film if required
- All holes & punches positioned, mounting, grounding, drainage
- Corner-key geometry, material and fit · installed or separate
- Cut-length & angle tolerances · packing and labelling requirements
Send the drawing as PDF plus CAD (DWG/DXF/STEP) where available. The TRX-AF product page shows how quotation and approval run from there.
