Dextra Manufacturing certified Green Industry

Dextra Green Industry

Dextra Manufacturing has been certified Green Industry (level 3) for its manufacturing facilities

The Green Industry certification is provided by the Ministry of Industry of Thailand to companies that show high commitment to environmentally-friendly entrepreneurship.


The Green industry certification is divided into 5 levels, which are

Level 1: Green Commitment is a commitment to reduce environmental impact and communicate internally.

Level 2: Green Activity is an implementation of activities to reduce the impact on the environment.

Level 3: Green System is related to systematic environmental management, monitoring, evaluation and review for continuous development.

Level 4: Green Culture is that everyone in the organization cooperates and works together in an environmentally friendly way, in all aspects of the business operations until becoming part of the corporate culture.

Level 5: Green Network is a demonstration of expanding the environmantally friendly way of operations throughout the business network by supporting partners and alliances to follow the Green Industry practices.

The continuous improvement of our production process goes hand in hand with our concern for the environment and the community where we operate.

Let’s all work together for a greener future!

New CAD/BIM tools for weldable couplers!

New CAD/BIM components of weldable couplers are available for AutoCAD, Revit and Tekla.

Weldable couplers are used for composite construction where concrete reinforcement bars must be welded to structural steel.

The couplers are specially made from low carbon steel and have a large chamfer for bevel welding.

You can download the component now for free!

Seismic performance tests in collaboration with Imperial College London

Large-scale beam-column tests incorporating Bartec/Fortec and Griptec couplers located at the expected plastic hinge zone, together with un-spliced rebar specimens, have been performed under loading simulating seismic load conditions.

Highlights of the test include:

  •    Both coupler systems allowed the development of ultimate rotation levels that are likely to be adequate for typical seismic design situations.

 •  The capacity was largely the same for all non-axially loaded members, suggesting that the use of Bartec/Fortec and Griptec couplers do not notably influence the member capacity.

The seismic performance of reinforced concrete members incorporating Dextra Bartec/Fortec and Griptec couplers

Ductility is a key performance characteristic for concrete reinforcement used in seismic design. The ductility of mechanical rebar splices, when used in seismic design, is therefore also extremely important and sometimes not sufficiently considered in product standards and testing practices.

Dextra recently collaborated with Imperial College London, in an experimental study and associated numerical assessment, into the performance of mechanical slices in dissipative regions of reinforced concrete members.

Monotonic and cyclic uniaxial ‘in-air’ and ‘in-concrete’ tests on 16mm and 20mm Bartec/Fortec and Griptec mechanical splices, as well as non-spliced reference members, were firstly performed.

After obtaining a detailed insight into the uniaxial behavior of the mechanical splices, large-scale beam-column members of 300×300mm square cross-section and 1,350mm cantilever length were tested.

The specimens were subjected to reversed cyclic lateral deformation, with or without co-existing axial load. Three specimens were provided with couplers in the expected plastic hinge zone while for comparison a fourth specimen had continuous longitudinal reinforcement.

Prior to the large-scale member tests, predictive numerical simulations were performed in order to steer the experimental assessment.

The load-deformation responses showed that both uniaxial “in air” and “in concrete” Griptec couplers seemed to provide marginally less ductility than Bartec/Fortec splices and non-spliced specimens.

However, it is thought that the ratios between coupler and rebar length considerably influenced the performance of the in-concrete tie members. The comparative assessment between in-air and in-concrete tests show lower ultimate deformations on in-concrete members in comparison with in-air samples.

For the large-scale beam-column tests, the capacity was largely the same for all non-axially loaded members, suggesting that the use of Bartec/Fortec and Griptec couplers does not notably influence the member capacity.

With regards to ductility, both coupler systems allowed the development of ultimate rotation levels that are likely to be adequate for typical seismic design situations, although Bartec/Fortec performed slightly better due to its shorter length.

Bulding homes, building hope

DBPG_Volunteering

Construction has always been at the core of Dextra, and what better way to celebrate it than helping someone in need!

“Habitat for Humanity” is an international NGO aiming to alleviate the housing issue for low-income families all around the world.

DBPG_volunteering_1

15 volunteers from Dextra brought their energy and enthusiasm to help building a home for Mr.Ye, a 70-year old farmer with a disabled son.

Dextra wants to warmly thank this great team of employees, and wish that this effort can result in a drastic life improvement for Mr.Ye and his family.

Annual outing fun at Dextra Guangzhou

DBPG Outing

In October, all employees at Dextra Guangzhou participated to the annual 3-day outing, organized this year in Guilin and Yangshuo, in the Guangxi province, China.

This region is particularly famous for the enchanting scenery, and our team enjoyed a long weekend of teambuilding games, bike rides and watergun action!

Collectivity and team spirit are essential for all Dextra employees. This special occasion was also an opportunity for the teams to spend time together among the relaxing atmosphere of the province.

Dextra at strategic seminar of the engineering community of Myanmar

Seminar Room

More than 200 members of the Federation of Myanmar Engineering Societies (Fed.MES), along with personalities from the local construction industry, attended a high-impact seminar organized by SKM Steels Limited, a strategic partner of Dextra in Myanmar.

DIN factory 3
The Federation of Myanmar Engineering Societies is the only engineering body that has a direct influence on all the engineers and consultants of the Country, thus making the event even more relevant.
Dextra had the unique chance of sharing its extensive knowledge on rebar couplers with an engaged and attentive audience.

Specifically, one of the main topics of discussion has been the benefit of using rebar couplers as a replacement to the classic rebar overlapping method.
Rebar couplers have been a household name in Europe and US for several decades now, and this construction methodology is gaining a lot of traction in South East Asia, where Dextra has already worked on some of the most iconic projects in the region.

The event was held on September 14th in Yangoon, Myanmar.
