Detailed Description
Aluminum 20 by 20 by 1.5 square tube racks 0.9 degree twist per 500 mm under asymmetric payload visible in horizon drift on long-exposure mapping passes. This square tube holds below 0.25 degree per 500 mm; corner filament runs continuous through the bend radius so the glue joint at the center-plate block sees compressive bearing, not peel. Slot widths for arm clamps held plus minus 0.07 mm so T-slot nuts drop without ream. Internal wipe of release film leaves clean bore for wiring pass-through. Guangdong Shenyang New Material supplies slot-coordinate inspection overlay PDF with every export batch.

FAQ
Q: Can slots be laser marked before cut to avoid ply damage
A: Laser scoring is done at low power on the peel-ply surface then the CNC follows the scored centerline for the slot.
Q: Internal wire passage liner or bare ID
A: Standard ships bare ID with release film wiped, PTFE liner is available for chafe-critical harness routes.
Q: Lengths 500 600 750 mm standard
A: All three lengths are held in semi-finished stock and finished lengths ship within 10 working days for repeat orders.
