Technical Terms

I Company No. 614060-A I

To facilitate better understanding of the business of our Group, the following glossary contains an explanation and description of certain terms used in this Prospectus in connection with our Group. The terms and their meanings may not correspond to standard industry meanings or usage of these
terms. “3-D” “angles”
“cementitious fire proofing” “channels” “cladding works”
“Dye Penetrant”
“girder” Three-dimensional

Steel beams with an L-shaped cross section
Long horizontal steel or concrete members, used to support weight in buildings or structures
A beam supported on only one end. The beam carries the load to the support where it is resisted by moment and shear stress. Cantilever construction allows for overhanging structures without external bracing
Refers to the act of making the steel structures more resistant to fire by applying or spraying cementitious products such as Vermiculite
Steel beams with an C-shaped cross section
Works related to the application of profiled metal sheets over a structure or bUilding to provide a skin or layer intended to control the infiltration of weather elements, or for aesthetic purposes
Computer Numeric Control. Refers to the automation of machine tools that are operated by abstractly programmed commands encoded on a storage medium
Refers to the joints between the main structural members. The joinUconnection must be capable of transferring all forces, loads across from one member to another
The process of drawing in outline or making a draft, sketch, or plan such as in architectural and mechanical drawings
Dye Penetrant Inspection is a widely applied inspection method used to locate surface-breaking defects in all non-porous materials such as steel. It is used to detect casting and forging defects, cracks, and leaks in the raw steel members
Ductwork is generally used for heating, ventilating, and air conditioning for a building
Engineering, procurement and construction. It is a common form of contracting arrangement within the construction industry. Under an EPC contract, the contractor will design the installation, procure the necessary materials and construct it, either through own labour or by subcontracting part of the work
The value-added process of construction equipment, machines and structures out of various raw materials, primarily steel. Fabrication generally involves the drilling, cutting, bending and welding of metal
The process of applying a metallic coating of zinc to steel. The two methods are Hot Dipping and Metal Spraying
Girder is the term generally used to denote the main horizontal support of a structure which supports smaller beams

“I-beams” “in situ”
“Magnetic Particle Inspection”
“metal decking”
“reinforcing bar”

“rolled sections”
“secondary steel”
“structural steel”
“tack weld”

“Ultrasonic Testing”


Grouting is the process of applying grout (a cementitious material, epoxy, etc.) to embed rebars or holding down bolts to a concrete surface. It is applied as a thick liquid and hardens over time, much like mortar
Steel beams with an I-shaped or H-shaped cross section
Generally refers to construction which is carried out at the building site using raw materials. In situ techniques are generally more labour­intensive, and time consuming. However, the work is versatile and adaptable
Insulation is used to reduce the transmission of heat or sound. Typically we insulate pipes carrying steam or hot water in order to reduce the heat being dissipated to the surrounding area
Used for the detection of surface and near-surface flaws of raw steel. A magnetic field is applied to the raw steel using a permanent magnet, electromagnet, flexible cables or hand-held prods. If the raw steel is sound, most of the magnetic flux is concentrated below its surface. If otherwise, the flux is distorted locally and ‘leaks’ from the surface in the region of the flaw
A profiled metal sheet which is laid across beams and combined with reinforced concrete which acts as the floor of a structure
Quality Assurance/Quality Control
A testing technique used in engineering to detect defects of weldment in structural steel by photographic techniques and using a source of energy, normally gamma rays
Also known as Rebar in short. It is a common steel bar used in reinforced concrete and reinforced building structures
Steel Plates that are rolled (by means of a rolling machine) to a certain curvature to form another object, eg a tank
Is a metal forming process where structural shapes are passed through rollers to bend or deform the workpiece to a desired shape while maintaining a constant cross-section. Structural shapes that can be rolled include: I-beams, H-beams, angle iron, channels, pipes, etc.
Steel members that together with the main members form the complete structure
Steel construction material formed with a specific shape and certain standards of strength as well as chem ical com position
Tack welding is used to set up the structural steel without using fixtures. Steelwork to be welded together are first positioned as required and tack welds are used as a temporary means to hold the components in the proper location, alignment, and distance apart, until final welding is completed
A structure comprising one or more triangular units constructed with straight slender members whose ends are connected at joints
A testing technique used in engineering to detect defects and cavities in structural members by sending a high frequency sound into the structural member from a probe
