Product Overview

KXD offers superior metal structure solutions for garage buildings and industrial facilities, providing significant advantages over traditional construction methods including 30% cost savings, 60% reduced construction time, 40% less weight, and nearly 80% resell value.

Pre-engineered Metal Building System

KXD's Pre-engineered Metal Buildings (PMB) feature primary members, secondary members, roof and wall sheeting connected to various building components. These structures can be customized with additions such as skylights, ventilation systems, doors, windows, trusses, mezzanine floors, and crane systems.

Key Advantages:
  • Economical cost structure
  • Factory-controlled quality
  • Enhanced durability and longevity
  • Flexibility in expansion
  • Environmentally friendly construction
  • Faster installation process

Applications: Factories, warehouses, showrooms, supermarkets, aircraft hangars, metro stations, offices, shopping malls, schools, hospitals, and community buildings.

Additional Systems

Crane Beams: Support members for different types of cranes allowing unobstructed movement along building length.

Mezzanine Systems: Standard systems consist of profiled steel deck, mezzanine joists, built-up beams and support columns.

Trusses: Rigid structures ideal for large span roof systems, multiple bay buildings and mezzanine floor framing.

Fascias and Canopies: Various types designed to enhance architectural appearance of buildings.

Secondary Members / Cold Formed Members

Secondary structural framing includes purlins, girts, eave struts, wind bracing, flange bracing, base angles, clips and miscellaneous structural parts.

Purlins & Girts: Roll-formed Z sections, 200mm deep with 64mm flanges and 16mm stiffening lip.

C Section: 200mm deep with 100mm flange and 24mm stiffening lip.

Eave Strut: 200mm deep with parallel flanges to roof slope, transmitting longitudinal wind forces.

Open Web Joists: Long span load-carrying trusses for direct support of floors and roof decks.

Cable Bracing: Extra high strength seven strand cable for building stability against wind, cranes and earthquakes.

Roof & Wall Panels

KXD standard steel panels are 0.3-0.6mm thick with minimum yield strength of 345 MPa, hot-dipped galvanized with zinc or zinc-aluminium coating.

Manufacturing Process

Steel plate cutting → H section assembly → Automatic welding → H section strengthening → Assembly → Manual welding → Shot blasting → Painting → Storage

I. Steel Plate Cutting

Professional setting-out workers ensure precise geometrical dimensions and tolerances. CNC cutting equipment preferred for quality assurance.

Portable CNC Fire-cutting machine: CNCDG-1530 - 5-100mm plate cutting thickness
Straight flame cutting machine: DZCG-4000A - 5-100mm plate cutting thickness
CNC cutting machine: CNC-4000C - 5-100mm plate cutting thickness
II. H Section Steel Assembly

Assembly on imported H section production line with hydraulic positioning system and CO2 gas shielded welding.

H section steel assembly machine: Z20B - Flange width 150-800mm, web height 160-2000mm
III. Automatic Welding

Gantry-type submerged arc automatic welding with preheating for ultra-thick plates.

Gantry-type submerged arc automatic welding machine: LHA5ZB - Maximum cross section 800mm×2000mm
IV. H Section Steel Strengthening

Correction of flange flatness and perpendicularity using specialized strengthening machines.

H section steel strengthening machine: YTJ60B - Flange width 200-1000mm
H section flange strengthening machine: HYJ-800 - Flange width 160-800mm
