Crash Barriers

Review Technical Documents

Our process begins by meticulously reviewing technical documents to ensure adherence to thrie beam crash barrier specifications and client requirements.

Raw Material Inspection

We conduct thorough inspections of raw materials, ensuring they meet the necessary standards for durability and performance.

Raw Material Testing (Mechanical & Chemical Test)

Raw materials undergo several mechanical and chemical tests to verify their properties, ensuring high-quality production and reliability.

Slitting

In this stage, large rolls of raw material are cut into narrow strips of precise widths to form barrier sections. This ensures precise dimensions and readiness for the subsequent forming stage and assembly.

Rolling

Steel coils are fed into rolling mills where they are shaped into specific profiles for thrie-beam production. This is the process that lends the necessary curvature and structural shape of the barriers.

Profiling

The barrier is cut into the exact length based on customer requirements to ensure proper fitment and performance of the product when installed. (is this the same as slitting)

Stamping

This step is done based on customer requirements and involves using dies to imprint specific designs or features onto the barrier surface.

Galvanising

• Pickling in Caustic Soda Solution HR coils are immersed in a caustic soda solution to remove any impurities and scale from the surface.
• Rinsing in Water House The coils are then rinsed thoroughly in a water house to remove residual caustic soda solution.
• Pickling in Acid Tank Next, the coils undergo pickling in an acid tank to further clean and prepare the surface for galvanisation.
• Rinsing in Water Tank Coils are rinsed again in a water tank to neutralise any remaining acid.
• Pre-fluxing This involves applying a flux solution to the surface of the coils, which helps in the adhesion of the zinc coating.
• Drying in Hot Chamber The coils are dried in a hot chamber to remove any moisture before galvanisation.
• Hot Dip Galvanisation in Zinc Bath The dried coils are immersed in a zinc bath at high temperatures, ensuring uniform surface coating of zinc.
• Cooling in Quenching Tank of White Water The galvanised coils are then cooled in a quenching tank filled with white water to solidify the zinc coating.
• Cooling in Quenching Tank of DI-Chromate Water The coils undergo further cooling in a quenching tank filled with DI-chromate water to enhance corrosion resistance and improve surface finish.

Finishing and quality checks

The finished coils are inspected for quality to ensure the galvanization coating layer is even and as required. Trimming is done if required to ensure the final producy dimensions. (CHECK THAT NO ROLL FORMING HERE AS PREVIOUSLY WRITTEN) Rigorous testing is also conducted while completing all the previously listed steps such as dimensional checks, visual inspections for defects, and testing for structural integrity of the barriers.

Packing

This stage involves packing the goods securely, labelling them correctly, and ensuring all required documentation (such as invoices and shipping labels) is completed. The goal is to ensure the items are protected during transit and all necessary information is provided for smooth delivery.

Despatch

Once packed, the goods are transferred to a shipping carrier or logistics provider. This phase includes managing logistics, tracking the shipment, and ensuring timely delivery to the destination, as well as handling any potential issues that may arise during transportation.
