Introduction

Description of the image

Steel beams called plate girders are frequently utilized in the building of bridges. The dimensions of the web, flanges, stiffness, and other metal components are chosen based on the design specifications and the structure itself.When creating a plate girder, the two most important things to consider are using the right material (steel) with the required strength and welding it together.When we require deeper sections with more stiffness to support large loads, we employ plate girders. With these details and the client's requirements in mind, we design the finest product we can for them. Our skilled staff members at Nony Industries Pvt. Ltd.'s Girder Fabrication Division are specialists in heavy fabrication and structural fabrication. With an ISO 9001:2015 certification, Nony Industries Pvt.

We have numerous machinery and equipment facilities for heavy fabrication. At Howrah Units, we have 6,000 m² of land and a 25000 m² covered manufacturing shed. Our total land area is 1,14,500 m².In Howrah, we have three factory units.

Design and Fabrication:

Plate girder services in Kolkata and West Bengal usually begin with the design and fabrication process. Experienced engineering firms in the area offer comprehensive design services, ensuring that plate girders meet the specific requirements of each project. This includes detailed structural analysis and adherence to relevant building codes and standards. Fabrication facilities equipped with modern machinery ensure precise manufacturing of plate girders to exact specifications. Train bridges across wide rivers and valleys are constructed with open web girders. In railroads, open web girders are typically 30.5, 45.7, 61.0, and 76.2 meters long. Both single and multiple cell girders are chosen based on the required width. Train bridges across wide rivers and valleys are constructed with open web girders.

Installing plate girders requires specialized knowledge and equipment. Professional plate girder services in Kolkata and West Bengal provide expert installation, ensuring that girders are properly positioned and secured according to the project's design specifications. Experienced teams handle the entire installation process efficiently and safely. A launching girder usually consists of main trusses (“girders”) and lifting devices that would move horizontally along the trusses while suspending/lifting the precast beam, bridge segments and/or working platforms for assembling.The Development Bureau, the Highways Department, and the Labour Department collaborated to produce the Guidelines on Safe Use of Lifting Frames and Launching Girders for Bridge Construction. Both the Department of Civil Engineering and Development

Maintenance and Repair:

Regular maintenance is crucial for ensuring the longevity and structural integrity of plate girders. Plate girder services in Kolkata and West Bengal also include maintenance and repair solutions. These services involve inspection, cleaning, and repair of any damage or wear to the girders, ensuring they continue to perform optimally throughout their lifespan. The guidelines on safe use of lifting frames and launching girders for bridge construction were produced in cooperation between the Development Bureau, the Highways Department, and the Labor Department. The Department of Development and Civil Engineering The lack of a document addressing the technical aspects of steel girders for railway bridges, such as maintenance and inspection procedures, was noticed while discussing the topic of steel girders for railway bridges in several IRICEN courses.The goal of this IRICEN publication is to close the knowledge gap and create documentation that Indian Railways civil engineers would find helpful, as over 90% of long span track bridges have steel superstructures.

Custom Solutions:

IEvery construction project is unique, and plate girder services in Kolkata and West Bengal understand the importance of providing custom solutions to meet specific project requirements. Whether it's designing girders for a new bridge or retrofitting existing structures, experienced engineering firms in the region offer tailored solutions to ensure the success of each project.The bottom chord, top chord, end rakers, diagonals, vertical members, and floor system, which consists of cross girders and rail bearers or stringers, are the main components of the girder. Train bridges across wide rivers and valleys are constructed with open web girders. In railroads, open web girders are typically 30.5, 45.7, 61.0, and 76.2 meters long. Both single and multiple cell girders are chosen based on the required width. In construction, a girder (/ˈɡɜ\rdər/) is a beam. Smaller beams are supported by it as the primary horizontal support of the construction. Girders can have a variety of shapes, including a box, Z, or I-beam cross section made up of two load-bearing flanges separated by a stabilizing web.

Quality Assurance:

Quality assurance is paramount in the construction industry. Plate girder services in Kolkata and West Bengal adhere to strict quality control measures throughout the design, fabrication, and installation processes. This ensures that plate girders meet the highest standards of quality and safety, providing clients with peace of mind and long-lasting results.Straight bridges between 33 and 650 feet (10 and 200 meters) in length, like light rail bridges, pedestrian overpasses, and highway fly-overs, are the most prevalent types of girder bridges. Brazil is home to the world's longest girder bridge, which spans 2,300 feet (700 meters). Girders are an essential component of any construction project that maintains structural soundness since they serve as the primary horizontal supports of a structure and aid in supporting smaller universal beams. Or to put it another way, a girder is a kind of beam.

Conclusion:

Description of the image

Plate girder services in Kolkata and West Bengal play a crucial role in the region's ongoing infrastructural development. From design and fabrication to installation, maintenance, and repair, these services offer comprehensive solutions for projects of all sizes. By partnering with experienced engineering firms, construction companies can ensure the successful completion of their projects while adhering to the highest standards of quality and safety. Large structures are mostly supported by girders, which also hold up the smaller beams. Girders have a far higher load-bearing capacity and are meant to serve as the main structural supports. They are able to support rolling and dynamic loads. In ladder decks, the deck slabs are supported primarily by the transverse cross-girders that run the length of the deck slab. Nonetheless, the secondary duty of keeping the slab from buckling under stress might fall on the girders.
