H型钢的翼缘都是等厚度的，有轧制截面，也有由3块板焊接组成的组合截面。工字钢都是轧制截面，翼缘内边有1：10坡度。Ｈ型钢的轧制不同于普通工字钢仅用一套水平轧辊，由于其翼缘较宽且无斜度(或斜度很小)，故须增设一组立式轧辊同时进行辊轧。TheflangeoftheHsteelisequalthickness,hasarollingcrosssection,andasectionof3plates.TheI-steelistherollingsection,andtheinneredgeoftheflangehasthe1:10gradient.TherollingofHsteelisdifferentfromordinaryI-beamonlywithasetofhorizontalrolls.Becauseofitswideflangeandnoslope(orvery***allslope),agroupofverticalrollersshouldbesetupandrolledatthesametime.板材是指一般的压型钢板\平板等,都是较薄的钢板,通常都作为屋面或围护墙等用型材是指热轧的\冷弯的如工字钢\H钢\C型钢Z型钢,通常都作主结构用。Platereferstothegeneralprofiledsteelplate,flatplate,etc.,whicharethinsteelplates,usuallyusedasroofingorretainingwalls.Profilesrefertohotrolledcold-formedones,suchasI-steel,\Hsteel,\CsteelandZsectionsteel,whichareusuallyusedformainstructure.装饰板材是所有板材的总称，主要有：细木工板、胶合板、装饰面板、密度板、集成材、刨花板、防火板、石膏板、PVC板、铝扣板、铝塑板、三维板等。Decorativeboardisthegeneralnameofallboard,mainly:board,plywood,decorativepanel,densityboard,integratedmaterial,particleboard,fireboard,plasterboard,PVCboard,aluminumplate,aluminumplasticboard,three-dimensionalboard,etc.)
