Pre-galvanized CHS (Circular Hollow Section) mapaipi achitsulo ozungulira omwe amafanana ndi BS1387 okhala ndi gulu la buluu amagwiritsidwa ntchito popanga zinthu zosiyanasiyana, kuphatikiza zomangira, mipanda, ndi zotchingira. Muyezo wa BS1387 umatchula zofunikira za machubu achitsulo opindika ndi zitsulo ndi machubu a machubu achitsulo osawoneka bwino oyenera kuwotcherera kapena kuwotcherera ku ulusi wa BS 21. "Blue gulu" limasonyeza kuti chitoliro ndi BS1387 sing'anga kukula kwake.
| Zogulitsa | Chitoliro chachitsulo cha Pre Galvanized | Kufotokozera |
| Zakuthupi | Chitsulo cha Carbon | Kutalika: 20-113 mm makulidwe: 0.8-2.2mm Utali: 5.8-6.0m |
| Gulu | Q195 = S195 | |
| Pamwamba | Zinc zokutira 30-100g / m2 | Kugwiritsa ntchito |
| Kutha | Zopanda mapeto | Greenhouse steel pipe Mpanda dongosolo chitsulo chitoliro Mipando zitsulo chitoliro Zida zolimbitsa thupi zitsulo chitoliro |
| Kapena Mapeto a Threaded |
Kulongedza ndi Kutumiza:
Tsatanetsatane Wolongedza : mu mitolo ya hexagonal yoyenera kunyanja yodzaza ndi zingwe zachitsulo, Zokhala ndi ma nayiloni awiri pamitolo iliyonse.
Zambiri Zotumizira : Kutengera QTY, nthawi zambiri mwezi umodzi.
