Izinga le-BS1139 le-scaffolding yensimbi, indinganiso esesikhathini eside, esetshenziswa kabanzi futhi esebenza emhlabeni wonke.I-Material grade S235GT ipayipi lensimbi elishiselwe isikhathi eside linobubanzi obungu-48.3mm, futhi lifakwe uthayela elishisayo ngaphakathi nangaphandle.Ngokwendlela yokuhlola ye-BS EN ISO, kuhlaziywa ukwakheka kwamakhemikhali e-carbon (C), i-silicon (Si), i-phosphorus (P), isulfure (S), i-nitrogen (N) nokunye okuqukethwe.Izici ezingokomzimba nezomshini zamapayipi ensimbi zihlolwa njengalokhu: amandla aqinile, isivuno kanye nokwelula.Ukusebenzisa amapayipi ensimbi esikafula ahlangabezana nezinga le-BS1139 kuyisinqumo esihle esinganciphisa ngempumelelo amathuba okuba izingozi zescaffold ezibangelwa izinkinga zekhwalithi yezinto ezibonakalayo.
