Abstract Nowadays, pre-engineered steel buildings (PEB), which are imported from foreign countries, become popular for the construction of factories and warehouses in Thailand. In most of the PEB projects in Thailand, the fabricated parts imported from foreign countries, have not been properly examined by the concerned Thai authorities or the third party. This study collects information about imported PEB steel structures. The method consists of site visiting and interviews of personnel in charge of design and construction of the imported PEB. In order to perform a comparative study on the quality of fabricated structures, international inspection standards for fabrication are adopted in this study. From the inspection results at five imported PEB construction sites, some defects in the steel structures are found as follows: 1) welding defects such as undercut, overlap and porosity, 2) defects in anchor bolt such as remaining screw length less than position of nut, 3) defects in the fabricated part, due to error of fabrication process such as distortion of area surrounding the holes and insufficient of coating thickness. The proposed countermeasures for quality control of fabricated steel structures were divided into two schemes as follows: (a) fabricator accreditation to classify the fabricator according to their capabilities. (b) checklist for inspection the quality of fabricated steel structures.
