works layout ensures efficient flow of steel from delivery into the stockyard through preparation, fabrication,
assembly, protective treatment to dispatch.
plates from the stockyard are blast cleaned and descaled prior to fabrication to remove rust, grease, and surface corrosion.
Having been transferred to the preparation workshop structural steel plates
are cut to size
and shape by the computer numerically controlled plate burning machinery using oxy-propane cutting.
The burning machines can process plates up to 21m long and 3.6m wide. The preparation workshop is equipped
with sawing lines, presses and rolls.
The fabrication bays are equipped with a variety of drilling and milling numerically controlled machinery to
cover the full range required for bridge and heavy structural components.
Each preparation, fabrication and assembly bay is serviced by overhead craneage with lifting capacity ranging from 5 to 32
I and box sections are assembled using the automatic or semi-automatic welding equipment.
The web to flange submerged arc welding is carried out under semi-automatic mode.
Panels assembly machines produce precise high-quality orthotropic deck panels.
components are then shot blasted and painted to provide the required protective treatment system to meet the
client's specification. These manufacturing processes are carried out using up-to-date machinery made in Finland
and Germany. After application of protective treatment, the bridge components arrive to the trial erection yard.
This outdoor area, served by travelling cranes with 60 metric tons lifting capacity, is used to trial erect
steel structures before delivery to construction site.
trial erection being finished, bridge steel structures are delivered to client by highway or railway transport.
