Frequently asked questions

Will the coupler pass GOST and lab testing?
Yes. Splice strength ≥95% of the bar's ultimate tensile strength, compliant with GOST 34278-2024. We provide the test report and a free trial kit for incoming inspection.
What does the price depend on?
On the diameter and batch volume. We send the current price for your project within the business day — usually below your current supplier.
Do you ship across Russia?
Yes, we ship to all regions of Russia and the CIS. Common sizes are from stock, the rest are made to order.
Why is a coupler better than welding or a lap splice?
The thread is rolled with no loss of cross-section, the splice is full-strength to the rebar body, installation is faster than welding and with no rebar overrun on lapping — savings of up to 25%. More — in comparing coupler / welding / lap splice.
