EN 10204 defines inspection document types for metallic products. Type 2.2 is a manufacturer's test report based on non-specific batch data. Type 3.1 is an inspection certificate with actual test results from the specific batch supplied, signed by the manufacturer's independent quality representative. Type 3.2 adds independent third-party or buyer-appointed verification — the highest assurance level under the standard, routinely required on oil and gas, offshore, and safety-critical projects.

Oxyfuel Cutting

Bandsaws dedicated to industrial metal-cutting use, such as for structural steel in fabrication shops and for bar stock in machine shops, are available in vertical and horizontal designs. Typical band speeds range from 40 ft/min (0.20 m/s) to 5,000 ft/min (25 m/s), although specialized bandsaws are built for friction cutting of hard metals and run band speeds of 15,000 ft/min (76 m/s). Metal-cutting bandsaws are usually equipped with brushes or brush wheels to prevent chips from becoming stuck in between the blade’s teeth. Systems that cool the blade with cutting fluid are also common equipment on metal-cutting bandsaws. The coolant washes away swarf and keeps the blade cool and lubricated.

Bandsaw Cutting

Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well. Plasma cutting is often used in fabrication shops, automotive repair and restoration, industrial construction, and salvage and scrapping operations. Due to the high speed and precision cuts combined with low cost, plasma cutting sees widespread use from large-scale industrial CNC applications down to small hobbyist shops.

Lumsden ground steel plate suppliers, delivering to the whole of the Middle East. Nifty Alloys supply ground steel plates in a wide variety of steel specifications. Lumsden ground steel plate is suited for applications that require a tighter tolerance than commercial hot rolled or sawn plates. With Lumsden ground steel the grinding offers a defined tolerance on thickness with a quality surface finish.

Flame cut profiles in mild steel and carbon steel grades can be Lumsden ground to your specific sizes on thickness with a standard tolerance of +/-0.25mm. If tighter tolerance is required please consult with our sales team as we may be able to offer a Lumsden ground tolerance of +/-0.10mm or a precision ground finish, dependent on the size of the steel plate required. Plates can also be edge machined to close tolerances. Machining costs and delivery time can be reduced by simultaneously grinding multiple steel plates, this also ensures a uniform thickness on all pieces.

Ground Steel Plate

Precision Ground Bar, also known as ‘Turned Ground and Polished’ shafting, refers to round bars made with fine precision and high-quality steel. They are polished to ensure flawless and perfectly straight surfaces. The manufacturing process is designed for extremely close tolerances for surface finish, roundness, hardness, and straightness which ensures a long service life with reduced maintenance. The precision ground bar is commonly used often used in applications that require high accuracies, such as weather measuring devices, laboratory tools, high-speed motor shafts, drive shafts, pump shafts, and ball bushings. In these scenarios, the bar is often required to rotate at high speeds. Thus extreme straightness is critical to prevent unwanted vibration and wear on bearings. Precision ground bar is manufactured through induction hardening.
