"NEW GRINDWEL" is a mutely owned global design, manufacturing and onsite service providing company of engineered splice solutions for the heavy construction industry. NG mechanical reinforcing bar couplers, anchorage, structural products, pre-cast connectors and similar value - added engineered splice systems offer a variety of solutions to meet the challenges of heavy construction as well as Industrial metal component too.
NG Powered by manufacturing and engineering capabilities, NG is committed to exceptional customer satisfaction, sustainable product initiatives and service quality at every job site. Because NG values our customers, we employ a dedicated staff of administrators, engineers, and technicians to ensure that we provide the best customer service possible.


Our Research and Development team is comprised of skilled Mechanical, Civil and Industrial Engineers. These dedicated professionals specialize in rebar splice solutions for challenging construction projects. In addition to the products in our catalogs, we can custom design special mechanical connectors and a variety of other engineered steel products to fit the needs of each project.
For large-scale projects, we also offer solutions for your rebar splice design problems.


NG production follows the guidelines established by our Quality Assurance Program and we are certified by an ISO 9001 Quality Management Systems accredited agency. Our certification was granted because quality and accountability are two major pillars in our production process. All of our materials, documents and processes are carefully filed for traceability and a tracing code is printed on each product we produce.
NG also manufactures rebar splicing solutions locally to avoid long lead times, transportation and customs issues, and the expenses of manufacturing abroad.

Quality Control Policy

Quality Control and Quality Assurance Systems provide sustainable quality for engineering, products and services.
Under the new Grindwel Quality Assurance Program, codes are stamped on all of our mechanical couplers. These codes allow the couplers to be traced back to the original lot of steel and the mill which produced it. Certified Material Test Reports ( CMTR ) is archived for future use as required. Each joint with New Grindwel RE-Bar couplers is designed to exceed 125% of the specified yield strength in the INDIA when used with Grade FE500 rebar's. Bar Break performance for all standards rebar's (D16 - D50).

Our each product are Designed and Manufactured in compliance with -

  • IS 1786:2008 ( Indian Standard )
  • Eurocode 2 ( Europe Standard )
  • BS 8110 ( British Standard )
  • DIN 1045 ( German Standard )
  • ACI 318 ( USA Standard )
  • GB 1499-91 ( Chaina ) & many more.

Why a Rebar Coupler / Mechanical Splice?
Due to the growing technical challenges faced in today's construction industry, traditional methods for connecting rebar, such as lapping or welding, are no longer the best methods to connect rebar. More and more construction codes are specifying a mechanical coupler because it provides better structural integrity while minimizing costs. Here you can find some benefits of using NG mechanical couplers listed below:

More reliable and more structural integrity than lap splices because they no longer rely on the concrete for load transfer.
Lowers the risk of rock and air pockets by reducing rebar congestion.
Efficient and easy design options result in smaller and stronger columns with the maximum amount of useful area.
Avoids drilling and / or cutting forms, especially in crane, elevator openings, and stairwells.
Installs easily and quickly.
Reduces the amount of rebar, which reduces the labor and crane time - improving the construction schedule.
No lapping length necessary - reduces inventory which lowers cost.
Better splice inspection - lowers quality control costs.
Allows for same line splicing - no staggered splices.
Minimizes rebar waste.
