PROFILE DEVELOPMENT / 10B21
10B21 10.8X14.8
10B21 10.8X14.8: Rectangular sample record. In this case, the catalog nominal cross-section is 10.8 × 14.8 mm; material designation is 10B21. Width-thickness orientation and corner geometry must still conform to the approved drawing.

Geometric Focus Points
Width, height, fillet radius, and width-to-thickness ratio
Width and thickness dimensions, edge profile, and straightness
Confirm technical requirements based on the drawing
Cross-sectional features and review points
This case has a catalog nominal cross-section of 10.8 × 14.8 mm, material grade 10B21. Width/thickness orientation and corner geometry must correspond to the approved drawing.
Drawings and measurement requirements
Clarify which direction corresponds to 10.8 and 14.8, and supplement bidirectional tolerances, corner requirements, and measurement locations; catalog values do not specify these acceptance criteria.
Delivery and subsequent processing
If subsequent operations involve oriented feeding, clamping, or forming, specify cross-sectional placement orientation, surface requirements, and coil vs. straight form.
Documentation basis and scope of confirmation
Data originates from this case’s catalog and internal sample photographs; catalog dimensions are nominal values, and photographs do not substitute formal inspection reports. Material standards, mechanical properties, heat treatment, supply conditions, and acceptance criteria must be confirmed per project.

Development Q&A
Does 10.8 × 14.8 mm already include dimensional tolerances?
No. This page retains catalog nominal dimensions; dimensional deviations, fillets, and inspection methods must be separately specified in the approved drawing or technical agreement.
How to avoid confusion between width and thickness directions for rectangular cross-sections?
Fix width-thickness nomenclature, cross-sectional orientation, and measurement datum in drawings and inspection records—and align downstream feeding orientation accordingly.
