15 m/min Production Speed 5.5 kW PLC Drive 300-450H Heavy Steel Chassis Roofing Roll Forming Machine for 840 IBR Roof Sheet Making

Developed through rigorous hands-on manufacturing experience and advanced structural engineering expertise, the howann Fully Automatic 840 IBR Floor Sheet Making Machine High Speed PLC Control with Motor & Pump for Building Materials is trusted by international builders across the United States, United Kingdom, Philippines, and South Korea. Designed to meet strict architectural load-bearing requirements, this heavy-duty system seamlessly converts flat metal coils into precision-profiled 840 IBR roof panels and composite structural floor decking.

Backed by strict ISO9001 manufacturing authoritativeness and full compliance with European CE safety directives, every machine undergoes mandatory factory test runs and video audit verification prior to dispatch. To ensure absolute customer trust and long-term operational security, howann provides transparent tiered wholesale pricing ranging from $4,850 to $5,750 per set alongside a comprehensive 2-year core warranty and responsive 24/7 technical support.

• Firsthand Jobsite Reliability: Designed alongside professional metal roofing contractors to eliminate material slippage and edge-cracking during high-speed rolling passes.
• Deep Metallurgical Expertise: Incorporates 45# chrome-plated forged steel rollers and high-hardness Cr12 tool steel cutting blades, preventing surface scratching on pre-painted color-coated coils.
• Certified International Authoritativeness: Manufactured in a certified 3,000 m² facility adhering to stringent ISO quality management protocols and EU safety standards.
• Uncompromised Transparent Trustworthiness: Supported by clear tiered pricing ($4,850–$5,750), secure escrow payment protection, and verified customer satisfaction ratings across global trade markets.
• Rigid 300-450H Frame Stability: A heavy 2,000 kg mass-damping chassis absorbs mechanical vibration, maintaining profile symmetry and wall-thickness uniformity over thousands of production meters.

• Coil Infeeding & Guidance: Galvanized or color-coated steel strips are fed smoothly from the 5-ton manual decoiler into the precision alignment guide table.
• Cold Roll Progressive Forming: Calibrated roller stands gradually press the metal through multi-stage passes, transforming flat sheets into rigid 840 IBR profiles without coating damage.
• Digital Length Measurement: High-precision rotary encoders track linear travel distance in real time, signaling the PLC unit when the exact programmed panel length is reached.
• Hydraulic Shear Cut-Off: The Cr12 tool steel hydraulic blade shears the formed panel instantly with clean, burr-free square edges, eliminating secondary trimming.

• Commercial & Industrial Warehousing: Fabricating weather-resistant 840 IBR roofing and wall cladding sheets for large-span industrial buildings.
• Composite Floor Decking: Producing rigid ribbed steel panels used as structural load-bearing bases in multi-story steel-frame construction.
• Regional Construction Supply Yards: Centralized manufacturing hubs supplying custom-cut metal roofing solutions directly to local contractors.
