Product Description
A36 Introduction
ASTM A36 is the most commonly used mild and hot-rolled steel. It has excellent welding properties and is suitable for grinding, punching, tapping, drilling and machining processes. Yield strength of ASTM A36 is less than that of cold roll C1018, thus enabling ASTM A36 to bend more readily than C1018. Normally, larger diameters in ASTM A36 are not produced since C1018 hot roll rounds are used.

A36 Carbon Steel Mounting Bracket Swivel  FlangeIntroduction

Mounting bracket swivel  flange is a core connector for scaffolding systems, compatible with standard 48/48.3mm steel tubes, widely applied in building construction, curtain wall support and pipeline fixing. It is integrally hot-forged from Q235 steel, free of pores and cracks, featuring superior tensile and impact resistance compared with cast couplers. Galvanized passivation surface effectively prevents rust under outdoor conditions.Equipped with Grade 8.8 high-tensile bolts for stable clamping, its 360° rotatable hinge fits cross tubes at any angle for diagonal bracing. The side set screw provides double locking to avoid sliding. Complying with GB/T15831 and EN74 standards, each batch passes anti-slip and breaking load tests with minimum failure load of 17kN. Complete material and mechanical test certificates are available for customs clearance. Stable mass production and protective packaging make it a reliable scaffolding fitting exported worldwide.

Product processing

A36 Carbon Steel Mounting Bracket Swivel  FlangeProduct Processing

1.Raw Material Cutting & InspectionHigh-quality Q235 carbon steel blanks are inspected for tensile strength before cutting. Defective blanks with cracks are eliminated to guarantee stable forging raw materials.

2.Integral Hot ForgingBlanks are heated and pressed into an integrated coupler body with cylinder and hinge in one stamping. No welding joints, no internal pores, delivering stronger load capacity than cast fittings.

3.CNC Machining & TappingPrecise drilling and tapping are processed for side set screw holes and hinge holes, ensuring perfect fit of Grade 8.8 high-strength bolts without slipping.

4.Galvanizing & PassivationElectro-galvanizing plus passivation forms uniform anti-rust coating to resist moisture and alkali corrosion on construction sites.

5.Mechanical Performance Batch TestRandom samples undergo anti-slip and breaking load tests to meet GB/T15831 and EN74 standards. Unqualified batches are fully reworked.

6.Final Inspection & PackingWorkers check coating, threads and rotation flexibility. Qualified couplers are packed with moisture-proof bags together with test certificates before shipment.
