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.

| Kapena Mapeto a Threaded |
Kulongedza ndi Kutumiza:
Tsatanetsatane Wolongedza : M'mitolo ya hexagonal yokwanira kunyanja yodzaza ndi zingwe zachitsulo, Zokhala ndi ma nayiloni awiri pamitolo iliyonse.
Tsatanetsatane Wotumiza : Kutengera QTY, nthawi zambiri mwezi umodzi.
