Designed for high-demand industrial fabrication environments, the Heavy Duty Steel D28 Welding Table with 45 Degree Angle Markings delivers reliable modular workholding for heavy-duty frame builds, truss manufacturing and angled-component assembly.

Each tabletop is manufactured from Q355 high-strength steel and processed with artificial stress-relieving aging plus heavy-duty back-reinforcing ribs to guarantee long-term geometric stability. Five-sided precision-machined D28 locating holes follow international dimensional standards for full compatibility with global D28 fixture systems.

Laser deep-engraved 45-degree angle markings offer stable visual datum for diagonal workpiece positioning. Plasma nitriding achieves high surface hardness against spatter impact and wear. Multiple dimension options, adjustable support legs and OEM marking services are offered. Material certificates, flatness and hole-pitch inspection documents can be provided for export-oriented industrial projects.

• Process: Laser Deep-Engraved. This is not ink printing or simple etching. The engraving penetrates the metal surface, and after nitriding, the lines are permanent. Weld slag grinding and wire brush cleaning will not remove the scale lines.
• Scale Content:
  • Metric millimeter scale in the X-Y direction
  • Multiple 45° diagonal reference lines, intersecting diagonally
  • Origin reference angle mark, facilitating direct placement of inclined frames and braces
• Important Note: The 45° is only a reference line and cannot replace angle measuring instruments; high-precision mass production still requires angle support calibration. The welding table itself cannot be tilted or flipped.
• Customizable Scale: 30°/60° lines can be added, imperial inch scale, CNC engraving process optional, customer logo engraving.

• Process: Plasma Nitriding
• Hardness: HV550-900; HV870 is possible for mold steel substrates
• Nitriding layer depth: 0.25-0.5mm
• Effects: Weld slag does not easily stick to the work surface; can be cleaned with a simple scraper; wear-resistant and resistant to minor impacts; reduces the probability of rusting.
• Pre-processing: Shot blasting to remove oxide scale from the steel plate, followed by CNC milling of the surface, and then nitriding.

• Standard Warranty: 12-month warranty on the welding table body, covering manufacturing defects not caused by human error
• Excludes: Damage from impacts, high-temperature welding burns, and loss of flatness of the welding table due to improper use
• Value-added: Warranty can be extended to 24-36 months for a fee; after-sales table surface precision repair and scraping services
