The Steel Construction Development Association has presented the first edition of the national standard GOST R «Self-drilling screws for building structures made of cold-formed galvanized steel sections. General specifications». This International Standard was first developed. The standard takes into account the results of scientific research, domestic and foreign experience in the use of such products.
The document includes the basic requirements for self-drilling screws for building structures made of galvanized profiles and their safe use, durability, as well as corrosion resistance.
The standard as an application contains a methodology for testing joints of thin-walled structures from galvanized cold-rolled sheet on self-drilling screws for shear, tension, tearing from the sheet and tearing through the washer.
The development of a new standard for self-drilling screws for lightweight steel thin-walled structures, according to Steel Construction Development Association participants, will protect the market from poor-quality fasteners.
The Steel Construction Development Association proposes to participate in the discussion of the draft of this GOST R in order to develop an effective document. The text of the draft standard, explanatory note and feedback form can be downloaded from the Steel Construction Development Association website.
