DIN 17100 ST37-2 I-beam

Date : 2016-10-14 15:12:43

Processing

Common St37-2 I-beam and light ST37-2 I-beam edge of the wing root cause gradual thinning, angled. Common ST37-2 I-beam and light ST37-2 I-beam model is with its high waist centimeters arabic numerals, different web and flange thickness and flange width specifications to waist high (h) × leg width (b) × waist thick (d) of the coin number. Common ST37-2 I-beam specifications are also available models indicated that the model represents a few centimeters high waist. if several different legs wide and thick waist, need to add a, b, c model to be different.
