PAO Severstal, one of the world's leading vertically integrated
steel and mining companies, in the framework of the development of steel
construction, initiated and participated in the development of a national
standard for the production frame and facing of walls of cold-formed steel
galvanized profiles for civil and industrial construction.
the Document was prepared with the support of the Association of steel construction development
(ARSS) and shall enter into force on 1 may 2020.
participation in the development of GOST R 58774-2019 "the Walls of the outer frame and facing
self-supporting and curtain with a frame of galvanized cold-formed steel
profiles," took the staff of Department of technical regulation of the Directorate of
technological development and the quality of the division "Severstal Russian steel". New
standard REGLEMENTARE unified requirements to the components frame and facing
the walls, the technology of production of such structures. In part of steel materials
have a minimum thickness galvanized steel profiles at least 0.7
mm grade zinc not less than 275. This will ensure the longevity of the design, and
requirements brackets for its fixing to the supporting elements of buildings and
structures.
"Severstal", as one of the founders of the Association for the development of the steel
construction, is interested in the development of national standards for
products and technologies involved in the construction with the use of steel.
the New document, developed with the participation of our specialists and ARSS, directed
to develop the technology of pre-fabricated buildings from light steel thin-walled
structures (lsts), already proven abroad. Compliance
the standard will give assurance as to market participants and end-users
reliability and safety in operation and high performance
characteristics and current level of energy efficiency," commented
Director of technical development and quality division "Severstal Russian
steel" Peter Mishnev.
the Entry into force of GOST R 58774-2019 will protect all market participants, including
the ultimate consumers from unscrupulous players and provide legal
basis for compliance with stated requirements, will increase confidence in the technology
LSTK.
background:
the Use of technology lsts construction requires a solid
Foundation, welding (due to the use of mounting bolts)
the use of powerful lifting equipment. The erection can
lead, regardless of the season. This, in turn, reduces the cost and
increases the speed of construction.
the Use of such structures also provides freedom of design, and
the modularity of the buildings provides the possibility of completion of the premises in the same style.
Application frame and facing of the walls allows to reach class energoeffektivnosti
buildings of class A++ and, consequently, savings on heating and
air conditioning.
