Economical Prefabricated Metal Frame Structure House

Economical Prefabricated Metal Frame Structure House 1. Common materials of steel structure frame building   H section steelH type steel is an economic efficient section material with optimized cross section area allocation and more reasonable ratio of strength to weight. It is named because of its letter "H" cross section. Since its different parts are of orthogonal configuration, h-beam has advantage of good bending capacity, simple construction, cost saving and structure light weight etc., has been widely used. H-beam is divided into: The flange wide type (HW) The flange middle type (HM) The narrow flange type (HN) Thin-wall h-beam type (HT) H section steel pile type (HU) H-type steel, optimized from I-shaped steel, is economic cross section steel with better cross-section mechanical performance. Especially, it is named because of its letter "H" shape section.    Its characteristics are as follows: (1) Wide flange, large latera…
