REBAR SPLICING

Standard coupler for rebar (Type B)

Ø16–40 mmGOST 34278-2024

The Lomax Type B standard rebar coupler — a full-strength threaded end-to-end splice of two same-diameter bars, without welding or lapping.

A base (standard) threaded coupler for joining two rebar bars of the same diameter. The thread is rolled onto the bar by machine without weakening the cross-section — the splice becomes full-strength to the rebar body. Made by LOMAX, shipping across Russia and to the CIS.

← All threaded cylindrical coupler types

In shortThe Type B standard coupler for rebar is the base cylindrical threaded coupler joining two bars of the same diameter (Ø16–40 mm, class A500C) end-to-end without welding or lapping. The thread is rolled onto the rebar without weakening the cross-section, and the splice becomes as strong as the bar body. Used as the main working splice in columns, walls and floor slabs of cast-in-place buildings per GOST 34278-2024.

Applications

The basic working joint of a cage: columns, walls, floor slabs and foundation slabs — wherever rebar of the same section is spliced.

Why it pays off with the LOMAX factory

In-house production

We cut and roll the threads ourselves — we don't resell imported systems (RollCon, Dextra, Bartec). That makes our price structurally lower.

Lower price than imported systems

Direct factory prices, proven over 3 years of supply. We'll beat your current supplier.

GOST 34278-2024 test report

Full-strength splice ≥95% Rm. We include the test report in the document package for the site.

Free trial kit

For incoming inspection and the lab — we remove the risk before the first delivery to site.

Shipping across Russia

From stock and to order, any region and the CIS. Common Ø sizes ship immediately.

Help with the specification

We'll match types and volume to your project and count the couplers from your drawings.

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.
How much is the Type B coupler?
From 85 ₽/pc (Ø16). The price depends on diameter and batch volume — we send the current price for your project within the business day.
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.
