Elevated Bridges Guard Railings for Airport Construction
Elevated Bridges Guard Railings are metal guard railings that are installed along elevated bridges and highways to provide added safety and security. They have several features including a galvanized steel frame, a modular design, and a wide range of colors and finishes. They are designed to be long-lasting and easy to install.
Pipe railing for bridges is a type of architectural railing system used to define and separate pathways or stairways. The main specifications used when constructing a pipe railing include the size, length and diameter of the pipes, the height of the rails and the types of supports used. The most common finishes used are powder coating and galvanizing, with the most popular colour options being black, white and metallic silver.
We supply and install steel railing for various Elevated Bridges / Curbside viaducts in the airport construction and expansion projects.
Main types of bridge safety railings include Pipe railings, tube railings and Beam railings.
Supply of Railing for Elevated Bridges / Curbside Viaduct can include fixation and painting as well as other services.

Typical metallic Pipe and Tube Railings Quality Reference
STEEL AND IRON MATERIAL used for our elevated bridge pipe and tube railing products
Tubing: ASTM A 513.
Pipe: ASTM A 53/A 53M, Type F or Type S, Grade A, Standard Weight.
Finish: Galvanized finish for exterior installations: ASTM A 36/A 36M.
Cast Iron material: Gray iron, ASTM A 48/A 48M, or malleable iron, ASTM A 47/A 47M.
Brackets, Flanges, and Anchors are cast or formed same metal material and finish as the bridge rails.
FASTENERS for Hot-Dip Galvanized Railings
Type 304 stainless-steel or hot-dip zinc-coated steel fasteners complying with ASTM A 153/A 153M or ASTM F 2329 for zinc coating.
We supply Steel Pipe and Tube Railings fabricated in accurately controlled processes and qualities to ensure safety use in viaducts / suspended bridges projects
Steel Pipe Railings are fabricated according to customers requirements for design, dimensions, member sizes and spacing, details, finish, and anchorage, but not less than that required to support structural loads.
metals are cut, drilled, and punched cleanly and accurately.
Burrs are removed and edges eased to a radius of approximately 1 mm unless otherwise indicated. No sharp or rough areas on exposed surfaces.
Form work true to line and level with accurate angles and surfaces.
Weep holes are provided where water may accumulate.
Cut, reinforce, drill, and tap as indicated to receive finish hardware, screws, and similar items.
Connections: Railings has either welded or nonwelded connections unless otherwise indicated.
Welded Connections: Cope components at connections to provide close fit, or use fittings designed for this purpose. Weld all around at connections, including at fittings.
Steel and Iron Railing Finishes
Galvanized Railings:
Hot-dip galvanizing of steel and iron railings, complies with ASTM A 123/A 123M for hot-dip galvanized railings.
Railings hardwares comply with ASTM A 153/A 153M for hot-dip galvanized hardware.
Vent and drain holes are filled that will be exposed in the finished Work, unless indicated to remain as weep holes, by plugging with zinc solder and filing off smooth.
For galvanized railings, we also provide hot-dip galvanized fittings, brackets, fasteners, sleeves, and other ferrous components.
Preparing Galvanized Railings for Shop Priming: After galvanizing, thoroughly clean railings of grease, dirt, oil, flux, and other foreign matter, and treat with etching cleaner.
Preparation for Shop Priming: Prepare uncoated ferrous-metal surfaces to comply with requirements indicated below:
1. Exterior Railings: SSPC-SP 6/NACE No. 3, "Commercial Blast Cleaning."
2. Railings Indicated to Receive Primers Specified in Division 9 Section "High Performance Coatings": SSPC-SP 6/NACE No. 3, "Commercial Blast Cleaning."
3. Other Railings: SSPC-SP 3, "Power Tool Cleaning."
Shop-Priming and Painting Finish: Comply with Division 9 Section "High-Performance Coatings." For priming and painting of galvanized steel surfaces by epoxy primers and polyurethane coatings systems.
