Steel tubes and bars from stock in Plovdiv
Max Metal supplies steel tubes and bars to the hydraulics, machine-building and energy industries. The catalogue has three groups of steel tubes (precision, seamless, chrome-plated) and three groups of bars (chrome-plated bars, round bars, continuous cast iron). The distribution centre in Plovdiv (7,500 m²) holds the stock and cuts to size on 5 AMADA machines.
Material selection questions
The most common questions when choosing tubes, bars, and materials for hydraulic and machining applications.
How do you choose between precision tubes and seamless steel tubes?
Precision tubes are the better fit when you need tighter dimensional tolerances, better control of the internal and external surface, and hydraulic or machining-oriented applications. Seamless steel tubes are often the better fit for broader industrial loads, boiler service, and customer-specific executions.
When should you choose hard chrome-plated bars instead of induction-hardened bars?
Pick by wear, corrosion and duty: hard chrome for a standard cylinder, an induction-hardened layer for higher wear resistance in heavily loaded cylinders. See the chrome-plated bars
When are calibrated round bars and peeled bars the right choice?
Both have h9 / h11 tolerance; they differ in surface: calibrated bars are bright and cold-drawn, peeled bars are straightened and oiled. See the steel round bars
What data is needed for an accurate technical quotation?
Send the product type, dimensions, material or standard, length, quantity, tolerance requirements, surface requirements, and requested delivery schedule. For cut-to-length orders, include the final cut size and the permitted deviations.
