The Valgro Grating Edge Deburring Machine is engineered for efficient and reliable removal of burrs and rough edges on grating panels — whether FRP (fibre-reinforced plastic) or metal. Designed to deliver uniform, safe, and finished edges, this machine ensures panels meet quality, appearance and safety standards.

Grating panels often emerge from cutting or fabrication processes with sharp edges, exposed fibres or unfinished surfaces which can impair durability or increase risk of injury. The Valgro Grating Edge Deburring Machine addresses these challenges by providing a dedicated edge-finishing solution capable of smoothing, rounding and cleaning panel edges with speed and consistency. The system is built to integrate into production lines for high-volume output while maintaining precision.

• Robust construction suited for industrial use and continuous operation

• Uniform edge treatment for improved safety (no sharp edges) and improved downstream performance (coating, installation)

• Suitable for high throughput: designed to handle panel feed, edge deburring and cleaning in an efficient workflow

• Improves panel finish quality and supports better edge integrity / fibre containment in FRP or better edge condition in metal grating

• Enhances product safety and reduces risk of injury from sharp or unfinished edges

• Improves aesthetics and finishing quality – smoother edges, fewer defects

• Reduces labour cost and time compared to manual edge finishing methods

• Supports coating, installation, or assembly by delivering panels with ready-finished edges

• Gives better durability (especially for FRP gratings) by limiting exposed fibres or poorly finished edges

• Deburring and edge finishing of FRP gratings used in flooring, platforms, walkways or industrial sections

• Finishing metal grating panels or architectural grating panels where edges must be smooth and safe

• Fabrication lines where grating panels are produced at scale and require consistent edge finish for installation or coating

• Construction, marine, petrochemical, industrial flooring sectors where grating safety and finish matter

Transform your gypsum board surface preparation process with the Valgro Gypsum Board Sanding Machine — built to deliver smooth, uniform sanding of gypsum wallboard surfaces, ready for paint or coverings. The machine ensures consistent surface quality while preserving board integrity and minimizing sound-absorption defects.

Improve the surface quality of hardened and tempered steel strips with the Valgro Wet Brushing Hard & Tempered Strip Machine — a dedicated wet-brushing solution designed for strip finishing where tight flatness and minimal material removal are required.

This wet-brushing machine uses rotating abrasive brushes under coolant to uniformly remove a thin layer (approximately 1-2 µm) from hardened or tempered steel strips. It’s designed to reduce surface roughness (from approx Ra 1.15 µm incoming down to Ra 0.12 µm) and remove loose scale, micro-irregularities or surface contamination, while preserving flatness (no camber or deformation). It includes a sealed brushing chamber with inspection windows for process monitoring.

• Designed for wet brushing of hardened/tempered strips, utilising coolant to manage heat and clean sweeping.

• Removes approx 1-2 µm of material to deliver a refined surface with low roughness (target Ra ≈ 0.12 µm).

• Vibration-free and stable operation with guarantee of no strip deformation or camber.

• Sealed machine housing with viewing windows for operator visibility.

• Low noise operation (< 80 dB) and power-efficient performance.

• Robust, heavy-duty construction built for continuous industrial strip processing.

• Consistently delivers high-quality strip surfaces with improved flatness and finish quality.

• Helps downstream processes (coating, cladding, bonding) by providing a better base surface condition.

• Wet process improves tool life and process cleanliness compared to dry brushing in certain contexts.

• Reduces operational defects such as strip camber or handling issues due to improved flatness.

• Suitable for high-volume industrial lines where reliability and repeatable results are essential.

• Surface preparation of hardened or tempered steel strips used in cladding, coating, bonding or roll-processing.

• Strip finishing where removal of light scale, annealing colours or micro defects is required before further processing.

• Heavy industrial strip lines where maintaining flatness and surface uniformity is critical (automotive, heavy fabrication, bearing strips, high-precision components).
