Standard Modular Brick vs. Structural Steel I-Beams
Comparing 2 standards across 14 specifications. 14 key differences identified.
Standard Modular Clay Brick under ASTM C216 is the benchmark face brick standard for architectural veneer construction. Manufactured to actual dimensions of 3-5/8 × 2-1/4 × 7-5/8 inches (92 × 57 × 194 mm), three modular brick courses with standard 3/8-inch mortar joints equal exactly 8.0 inches in vertical height, perfectly matching the 8-inch height of backing CMU blocks.
Structural steel I-beams standardized under the American Institute of Steel Construction (AISC 360) and ASTM A6 / ASTM A992 are hot-rolled load-bearing beams. Classified into Wide Flange W-Shapes (parallel inner and outer flange faces) and American Standard S-Shapes (tapered 16.67% inner flange slope), beam callouts designate nominal depth and weight in pounds per foot (e.g., W12×50).
