Carbon Steel Plate Supplier in Saudi Arabia
RPF Pipes & Fittings is a prominent manufacturer, and stockholder of Carbon Steel Plates in Riyadh, Saudi Arabia. We supply a wide range of CS plates in an array of lengths, widths, and thickness according to ASME SA516 Carbon Steel standards, ideal for boiler and pressure vessel and storage tank fabrication. We produce these ASTM A516| ASME SA516} Grade 70 NACE MR0175 Plate using high-quality raw materials and advanced technology equipment following globally approved quality standards.
The ASTM A516 is the Standard Specification for Pressure Vessel Plates, CS, for moderate and lower temperature applications for plates used in pressure vessel applications where outstanding notch toughness is required. The ASTM A516 Carbon Steel Plates are divided into four grades having minimum Tensile Strengths ranging from 55 ksi to 70 ksi.
Our X120Mn12 Manganese Steel Plates are suitable for uses where severe wear is combined with shocks or high pressure capable of work-hardened its austenitic structure. High Manganese Wear Resistant Steel Plates are utilized in jaws of crushers, stone or iron chutes, liners of shot blasting units, cores and walls of parpen molds, and tumbling machines.
AS ASTM A387 GR 5 CL. 1 Plates exhibit several properties like good weldability, high performance, durability, excellent toughness, anti-corrosion, hydrogen stress cracking resistance, etc.
Our ASME SA387 Grade 5 CL.1 / 2 Pressure Vessel Plates are utilized in many applications like Bridges, Buildings and Construction, Automotive and Truck Parts, Railroad Cars, Cargo Containers, Tote Boxes, Construction Equipment, Structural Tubing, Lighting Standards, Transmission Poles, etc.
The ASTM A516 Carbon Steel plates come with mill certification in accordance with EN10204 3.1 or EN10204 3.2. Our plates are fully traceable, usually with hard stamping and we welcome any third party or customer inspection if required which can be arranged with the client.

CARBON STEEL PLATE FEATURES
Tensile strength is usually the first thing buyers ask about for pressure equipment. ASTM A516 grades give a minimum tensile strength of 55 ksi to 70 ksi depending on grade, which gives designers a reasonable margin for boiler and vessel loads. Weldability holds up well too. The carbon and manganese balance in these grades means welders don’t run into preheat issues on standard thicknesses, so fabrication on site moves faster.
Machinability is fine during drilling, shearing and forming, so shops can go from plate to finished part without burning through tools. Corrosion resistance gets better in NACE MR0175 and HIC-tested variants, which are built for sour service conditions common in Gulf oil and gas work. Pressure resistance and long service life go together here; these plates take repeated pressure cycling in vessels and tanks without fatigue cracking over years of use. Dimensional accuracy across thickness, width and length stays within tight bands, which cuts down on rework at the fabrication stage.

Why Choose Us as Your CS Steel Plate Supplier in Saudi Arabia?
RPF Pipes & Fittings supplies carbon steel plates worldwide from stock, not from a make-to-order queue. You can look through our full grade catalogue and specifications. A CS plate supplier in Saudi Arabia that keeps large volumes on the shelf means a project can move from order to site without a three-month wait for production.
Our inventory covers most major carbon steel grades in multiple thicknesses, so mixed grade orders can ship together instead of arriving in staggered batches. Every plate meets ASTM, ASME or EN standards, checked against certified mill test reports before it leaves. Export paperwork and freight bookings get handled internally, which saves buyers the time usually spent chasing forwarders. Our team can help with grade selection, tolerance queries and general application questions before an order gets placed. Pricing stays reasonable because we buy raw material in bulk and pass that on rather than sitting on the margin.
Third party inspection can be arranged through recognised agencies on request, and mill test certificates under EN10204 3.1 or 3.2 go out with every shipment. Custom cutting to size cuts down on-site waste, and our logistics network covers sea and air freight to ports across the Kingdom.
