Kusankhidwa kwa matabwa a H kuyenera kukhazikitsidwa pazinthu zitatu zomwe sizingakambirane, chifukwa izi zimagwirizana mwachindunji ngati mankhwalawo angakwaniritse zofunikira zamapangidwe.
Maphunziro a Zinthu: Zida zodziwika bwino za matabwa a H ndi chitsulo chopangidwa ndi mpweya (mongaMtengo wa Q235B, Q355B Hm'miyezo yaku China, kapenaA36, A572 H Mtengomu miyezo ya ku America) ndi chitsulo chochepa cha alloy champhamvu kwambiri. Q235B/A36 H Beam ndiyoyenera kumanga wamba (mwachitsanzo, nyumba zogona, mafakitale ang'onoang'ono) chifukwa chakuwotcherera kwake komanso kutsika mtengo; Q355B/A572, yokhala ndi mphamvu zokolola zambiri (≥355MPa) komanso mphamvu zokhazikika, imakondedwa pama projekiti olemetsa monga milatho, malo ochitiramo misonkhano yayikulu, ndi zida zomangira zokwera, chifukwa zimatha kuchepetsa kukula kwa mtanda ndikusunga malo.
Dimensional Specifications: Mitengo ya H imatanthauzidwa ndi miyeso itatu yayikulu: kutalika (H), m'lifupi (B), ndi makulidwe a intaneti (d). Mwachitsanzo, mtengo wa H wolembedwa "H300×150×6×8"Amatanthauza kuti ali ndi kutalika kwa 300mm, m'lifupi mwake 150mm, makulidwe a ukonde wa 6mm, ndi makulidwe a flange a 8mm. Miyendo yaying'ono H (H≤200mm) imagwiritsidwa ntchito pazigawo zachiwiri monga zolumikizira pansi ndi zothandizira kugawa; zazikulu zapakatikati (200mm＜H＜H＜400mm) denga lanyumba zazikuluzikulu za fakitale zimagwiritsidwa ntchito Miyendo ya H (H≥400mm) ndiyofunikira pazitali zazitali kwambiri, milatho yayitali, ndi nsanja zamafakitale.
Mechanical Magwiridwe: Yang'anani pazizindikiro monga kulimba kwa zokolola, kulimba kwamphamvu, komanso kulimba kwamphamvu. Kwa mapulojekiti omwe ali m'madera ozizira (mwachitsanzo, kumpoto kwa China, Canada), matabwa a H ayenera kudutsa mayesero otsika kutentha (monga -40 ℃ kulimba kwamphamvu ≥34J) kupewa kusweka kwa chiwopsezo m'mikhalidwe yozizira; kwa madera a chivomezi, zinthu zokhala ndi ductility zabwino (elongation ≥20%) ziyenera kusankhidwa kuti zithandizire kukana kwa chivomezi.
