What international standards apply to exported tie rod system products?

As important formwork accessories for export,tie rod system products have clear international standard specifications,which are mainly based on British BS series standards and European EN standards,and are widely recognized in Commonwealth countries,European regions and global international engineering projects.Different from domestic standard products,export-type tie rod systems have stricter requirements on rod body straightness,thread precision,tensile strength and accessory matching accuracy.British standard tie rod systems adopt unified inch dimensional parameters,matching British-type scaffolding and formwork systems,with fixed tensile load grades corresponding to different diameters.European EN standard tie rod systems focus on material mechanical performance and fatigue resistance,requiring products to maintain stable tensile performance after multiple turnover uses.Before export,tie rod system products need to complete third-party mechanical tests,including ultimate tensile strength test,repeated locking fatigue test and thread matching precision test,and provide official test reports to meet overseas customer acceptance and project filing requirements.In terms of surface treatment,export products mostly adopt hot-dip galvanizing anti-corrosion technology,which adapts to long-distance sea transportation and humid overseas construction environments,avoids rust damage during transportation and use,and improves product service life.Waterproof tie rod systems for overseas water conservancy and underground projects also need to pass professional waterproof performance tests to ensure that the water stop structure meets international building waterproof standards.Exporters need to classify products according to target market standards,distinguish British standard and European standard specifications,and avoid parameter mismatch leading to customer returns and project delays.In international bidding projects,the standard compliance of tie rod system is an important evaluation index of product qualification.Strictly implementing international standard production and testing can improve the market competitiveness of tie rod system export products and meet the safety and quality requirements of global construction engineering.
