旧金山新湾大桥

旧金山新湾大桥

The New Bay Bridge was a large civil engineering project undertaken between 2002 and 2013. The aim of the project was to replace two segments of the Bay Bridge that were vulnerable to earthquakes with a new structure designed to withstand seismic forces.

For this project, Dextra was involved in two segments of the renovation: the approach to the Bay Bridge on the San Francisco side and the eastern segment from Yerba Buena Island to Oakland.

Dextra 提供 巴特克® Headed Bar systems for this project. Headed Bars feature an anchor disc mounted on the end of a rebar previously prepared for the Bartec® system.

指某东西的用途 钢筋锚固板 provides a smart and compact alternative to long rebar hooks in areas where reinforcement is particularly congested. Unlike hook bars, Headed Bars are easy to install, as end anchors can simply be screwed onto the reinforcement at a later stage, after the reinforcement is in place.

For the approach to the Bay Bridge in San Francisco and the eastern segment of Yerba Buena Island, Bartec® Headed Bars were used for shear reinforcement in the column foundations as well as in the bridge hinges.

The Bartec® Headed Bars solution is approved by Caltrans (the California Department of Transportation) for all imperial bar sizes #3 to #18 and is also certified by the ICC-ES.

河内一新桥

河内 Nhật Tân 大桥(越日友谊大桥)

The Nhat Tan Bridge is an impressive cable-stayed bridge spanning the Red River, located north of Hanoi. The total length of the project is 8.9 km, including the 3.75 km main bridge.

The bridge serves as a new gateway to Hanoi, significantly reducing travel time to Noi Bai International Airport, the second busiest airport in Vietnam by passenger volume.

The bridge was inaugurated by the Ministry of Transport of Vietnam and opened to the public on January 4, 2015. It has since been renamed the “Vietnam – Japan Friendship Bridge.”

Dextra has been involved in the Nhat Tan Bridge since the early stages of the project, supplying the widely used 巴特克® rebar couplers, the leading rebar splicing solution in Vietnam. Bartec® connections were used in various parts of the project, including approaches, foundation piles, pile caps, and bridge segments.

Bartec® couplers offer a versatile rebar splicing solution, as the same standard coupler can be used for both standard connections (where the rebar rotates into the coupler) and position connections (where only the coupler rotates, useful when rebar rotation is not possible). Dextra supplied more than 130,000 connections in total for this project, enabling the lifting of heavy elements.

For the temporary operations of lifting and securing the precast girder segments, Dextra also supplied 36 tons of high-tensile PT棒.

Orbit by Auro Realty, Hyderabad, India

Orbit by Auro Realty, Hyderabad, India

采用预制技术建造的印度最高商业建筑

Orbit is a 25-storey office building strategically located in the heart of Hyderabad’s IT Hub, constructed using precast technology. It is one of the tallest commercial buildings in India built with this method.

Constructed by Aurobindo Realty, the Orbit building was honored with the “Best Office Architecture India” award by the International Property Awards – Asia Pacific Property Awards 2018.

Designed with precast technology, the building is also proposed for LEED v4 Gold Certification from USGBC, demonstrating its commitment to environmental sustainability and energy efficiency.

Dextra的 格鲁泰克 couplers played a key role in precast element connections. Approximately 60,000 couplers were installed in precast elements at the precast factory before being transported to the construction site for grout connections.

With the growing demand for modular buildings worldwide—especially during the COVID-19 pandemic, where healthcare and quarantine facilities were urgently needed—格鲁泰克 couplers have become a widely adopted solution. They are designed and manufactured in compliance with Eurocode 2, BS 8110, ACI 318, IBC, and AASHTO standards.

新尚普兰桥

新尚普兰桥

The New Champlain Bridge is a 3 km-long bridge spanning the Saint Lawrence River at the southeastern entrance of Montreal, Quebec, Canada. As one of the busiest bridges in Canada, it plays a crucial economic role for the city, serving as a key route to the United States, located 60 km south.

 

Replacing the Older Champlain Bridge

The New Champlain Bridge is replacing the existing Champlain Bridge, which was commissioned in June 1962. The older structure began showing signs of corrosion in 1994. After several temporary safety measures were implemented to keep the bridge operational, a replacement project was initiated in 2007. For a time, both bridges will stand side by side until the older structure is fully dismantled, with most of its materials planned for recycling.

 

A Focus on Corrosion Resistance

The New Champlain Bridge is designed to last at least 125 years and accommodate 50 million vehicle crossings per year. Given the corrosive environment caused by frequent road de-icing, corrosion resistance was a top priority. Duplex stainless steel rebar was installed in critical areas to enhance durability.

For this project, Dextra recommended using Duplex Stainless Steel Rolltec couplers and anchors. This specialized version of our Rolltec® system replaces standard couplers and anchors with an improved duplex steel alternative, offering superior corrosion resistance.

The Rolltec® solution is well-suited to the Canadian market and is approved by the Quebec Ministry of Transport. With a single-operator threading machine and 30-second threading cycles, it provides high productivity, making it ideal for high-labor-cost markets like Canada.

More than 10,000 Stainless Rolltec® couplers were supplied for this project, primarily for bridge spans. These couplers were used to splice large-diameter reinforcement bars, ranging from 35M (#11) to 55M (#18)—the largest size available in our Rolltec® range.

Additionally, about 10,000 Rolltec® stainless steel end anchors were delivered for sizes up to 55M (#18). Rolltec® Headed Bars use the same threading system as the couplers, simplifying production and installation.
