Incazelo emfushane:

Insimbi brace ilungele uphahla nodonga imishayo yensimbi yokwakha ubunjiniyela. Ukuqondisa ngokuvamile kubhekisa ensimbi eyindilinga ebopha ama-purlins wensimbi, okusho ukuthi imigoqo yensimbi eshisiwe, ukuqinisa ukusimama kwama-purlins nokwenza ama-purlins angathambeki kakhulu ekungazinzileni nasekulimaleni ngaphansi kwamandla athile angaphandle. Kukhona ama-brace e-diagonal (isb. 45-degree bending at the screw thread) nama-brace aqondile (okusho ukuthi konke kuqondile). Ngemuva kokwelashwa okushisayo kwe-galvanizing, umphumela we-antirust utholakala.
