Manufactured under stringent quality measures, the wooden flanges are made of chemically treated, seasoned timber. Using a unique finger jointing method, the webs are manufactured by joining these flanges with boiling water-proof plywood. STRUCTURAL PROPERTIES BEAM MAX. Q MAX. M EI H-16 6 KN 3 KN.M 145 KN. M2 H-20 11 KN 5 KN.M 350 KN. M2 M = Bending Moment Q = Shear Force E = Modulus of Elasticity I = Moment of Inertia H-beams consume less timber, as low as 40% of the required timber volume. Hence, they are light, dimensionally stable and retain their structural properties over a period of time, even after continual usage. They are more predictable, easy to design and use. H-beams can be used and reused nearly 100 times, which is 8 times greater than conventional timber. 80 MM 40 MM 65 MM 35 MM H-beams are available in two sizes namely H-16 (16 cms depth) and H-20 (20 cms depth). The length varies between 1m to 4.00m for H-16 and upto 4.80m for H-20.
