CNC Automatic Horizontal Band Saw For Infrastructure Construction Steel Cutting
The GZ4240 CNC Automatic Horizontal Band Saw is a robust cutting solution designed specifically for the infrastructure construction industry. With a cutting capacity of φ400 mm for round materials and 400 mm for square materials, this heavy-duty band saw is ideal for processing structural steel, reinforcing bars (rebar), foundation piles, bridge components, and other construction materials.
Built to withstand demanding construction site conditions and steel fabrication workshops, the GZ4240 features a dual-column structure and steel plate welded frame that has undergone vibration aging treatment for exceptional stability. The hydraulic feeding system with optical ruler positioning ensures precise material indexing for consistent component lengths, critical for infrastructure projects where dimensional accuracy directly impacts structural integrity.
The machine's bundle cutting capability allows multiple materials to be cut simultaneously, significantly increasing productivity for large-scale construction projects. With four-speed blade selection (25/35/50/65 m/min), hydraulic infinitely variable feed rate control, and automatic blade break detection, the GZ4240 delivers the reliability and efficiency required for continuous operation in infrastructure material preparation.

Applications
Bridge Construction
For bridge projects, the GZ4240 cuts steel beams, support columns, and reinforcement bars with consistent accuracy. The bundle cutting capability allows multiple rebar to be cut simultaneously, accelerating bridge deck and pier reinforcement preparation.
Highway and Railway Infrastructure
Road and rail construction projects require large quantities of steel components for guardrails, sign structures, and track supports. The GZ4240 delivers high-volume cutting efficiency with hydraulic feeding and automatic discharge for continuous material processing.
Building and High-Rise Construction
Steel frame buildings and high-rise structures require precise cutting of columns, beams, and bracing members. The GZ4240's ±0.2 mm cutting tolerance ensures components fit accurately during assembly, reducing on-site adjustments and welding time.
FAQ for Infrastructure Applications
Q1: What construction materials can the GZ4240 cut?
A: The GZ4240 is designed for cutting structural steel, reinforcing bars (rebar), carbon steel, alloy steel, and other ferrous metals commonly used in bridge, highway, building, and foundation construction.
Q2: Can the machine cut multiple rebars at once?
A: Yes, the machine is equipped with a bundle cutting device. Within the clamping width and height limits, multiple rebar or structural sections can be placed side by side for simultaneous cutting, significantly increasing productivity.
Q3: How accurate is the cutting for structural components?
A: The GZ4240 delivers cutting length tolerance of ±0.2 mm, ensuring consistent component lengths for structural assemblies and reducing on-site adjustments.
Q4: What is the maximum material size the machine can handle?
A: The machine can cut round materials up to φ400 mm and square materials up to 400 mm, suitable for most structural steel sections used in infrastructure projects.
Q5: How does the automatic discharge work?
A: The machine features a 40° sloping discharge port. After cutting, finished materials automatically roll into collection bins, reducing manual handling and improving workflow efficiency.
Q6: What power supply is required?
A: The machine operates on 380V / 50Hz / 3Phase power supply, standard for industrial facilities and steel fabrication shops.
