PC Production Line

PC (Prefabricated Concrete)—PC is short for Precast Concrete, it is mainly consisted of Prefabricated Components, through assembly, connection, partial cast-in-situ concrete structure, is the strong engine of the industrialized building development.

The implement of PC technology is the core content of housing industrialization, also is an important feature in housing modernization. Adopting modern industrial production method, the PC technology systematically integrates different stages and production factors together, by doing so, we can manage to standardize the construction designs, industrialize the components production, better housing elements designs. This also makes automatic assembling, integrated arrangement and decoration possible, moreover, to socialize production and operation so as to form a complete industrial production line. As a result, we would be able to improve housing quality, efficiency, resistance and reduce cost as well as energy consumption.


Introduction to PC Construction Technology

PC technology is our familiar prefabricated assembly technology, that is, in the factory prefabricated production, assembled in the field into a whole building. The PC implements the building from the factory-site-assembled industrial model.

The assembling of PC wall panels means connecting them together to form a structure with cast-in–situ-concrete; the structure is usually cast–situ-concrete or precast and cast-situ hybrid concrete structure. Commonly used PC products includes shear wall (exterior wall panel and interior wall panel), laminated floor slab, partition wall, stairs, balcony and so on.

Combining decoration, insulation, waterproof, pipeline system and door & windows system together, our products obtains extra added value while the quality is greatly improved as well


  • Walltec walls offer lower initial as well as long-term costs when compared with other materials due to low product costs, elimination of plaster, no curing, no zari- work for conduiting, no lintels, no stone sills, no maintenance, no flaking/cracks, increased carpet area as well as flexibility to move partition walls when required.
  • Lighter weight of the walls allows for lower deadweight thus reducing structural steel costs.

Ease of Installation & Efficiency

  • Walltec walls are factory made, transported to the site ready to install on pallets and manually erected on concrete floors. Highly versatile and fast to install, requiring just two regular construction workers to install up to 6 m2 per hour and are pre- cured thus do not require any curing. Can be cut, sawn and dimensioned as per requirement for installation at site.
  • Projects utilizing Walltec walls can save weeks or months over other materials due to no prep work, fast installation, no curing time requirement and time saving with plumbing, electrical and HVAC conduiting.

Aesthetically & Functionally Beneficial

  • On account of their factory finish they are aesthetically pleasing.Due to its availability in different heights and thicknesses with no load-bearing application it provides total design flexibility.
  • More carpet area due to lower thickness of 68mm to 140mm instead of brick partitions of 150mm with plaster on both sides.
  • No lintels need to be cast as panels can be place horizontally as lintels where required.
  • Due to its consistent line, length and levels Walltec walls do not require stone or wood sills/frames to level surfaces for windows and openings.
  • Hanging wash-basins, cup-boards, mirrors, paintings with regular plug screws possible and can take as much as 350kg of load. Drilling, Nailing, Hammering as in any normal brick-plaster wall.
  • Good workability, Less mess in installation, no curing, minimum waste at site and quick installation contribute to better site management.

Low Maintenance

  • No problems like leaching of salts from bricks over time. No cracking, flaking of plaster due to one homogeneous material. No plastering means additional saving on time, quality, maintenance etc.

Superior strength & durability

  • Strength gradually increases over time with an initial cube compressive strength of 25 to 40 N/mm2 and an initial sectional compressive strength of 18 to 30 N/ mm2.
  • Walls do not deteriorate, experience creep and stress relaxation, lose strength and/or deflect over time.

Safety & Protection

  • Provides excellent protection against impacts from intrusion, slamming, explosions, vehicles and projectiles.
  • High fire ratings of upto 2 hours.
  • Sound insulation of 46 – 50 dB
  • Have passed tornado/hurricane/heavyrain-sleet-hail impact testing,giving owners an added level of safety assurance in areas prone to severe weather.

Consistent Quality

  • Because precast concrete products are typically produced in a controlled plant environment, they exhibit high quality and uniformity.
  • Problems affecting quality typically found on a job site – temperature, curing conditions, craftsmanship and material quality – are nearly eliminated in a plant environment.

Environment friendly

  • No curing means massive water savings during construction.
  • Lower raw material used than with other partitions and all raw material composed of natural materials that are nontoxic and environmentally safe.
  • Lower raw material used than with other partitions and all raw material composed of natural materials that are nontoxic and environmentally safe.

Weather and UV Resistance

  • Walltec walls do not degrade from exposure to sunlight and provide excellent thermal shielding due to the hollows acting as heat sinks. Provides Thermal resistance of 0.4 (m2K)/W and better.
  • Can use insulation between 2 walls for added thermal resistance. 2 – 68 mm Walltec Panels sandwich a 10mm thermocol sheet to provide a partition wall with excellent thermal resistance.
