Products 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.
Carbon Steel A36 Galvanized Elbow Introduction
Carbon Steel A36 Galvanized Elbow, also known as key clamp 90 degree elbow fitting, is a cast pipe connector made of A36 carbon steel. It adopts composite zinc coating treatment combining electro-galvanizing and hot-dip galvanizing, with a total zinc coating thickness up to 80μm. This thick composite zinc layer offers outstanding rust-proof and anti-corrosion performance, effectively protecting the A36 carbon steel substrate from oxidation, moisture and atmospheric corrosion, and can serve stably in outdoor and humid environments.
This elbow fitting features an integrated 90° bent cast structure, with two socket openings for inserting round pipes at right angles. Two built-in threaded locking bosses are reserved on the fitting body, matched with hex socket set screws. When tightening the set screws, the inserted pipes can be firmly clamped to achieve non-welding, quick and stable assembly. Model specification marks are cast on the outer surface for easy identification.
It is designed to fit standard round pipe sizes, widely used for handrails, guardrails, scaffolding frames, stage structures, pipe support frames and other modular frame construction projects. The A36 carbon steel material provides high structural strength, the fitting is easy to assemble and disassemble, and has a long service life as a reliable modular pipe connection component.

Carbon Steel A36 Galvanized Elbow Product Processing
1.Raw Material Inspection & Mould Preparation
Select A36 carbon steel as raw material. Perform strict incoming inspection on chemical composition, tensile strength and yield strength, reject materials with impurities and internal defects. Prepare casting moulds engraved with product specification marks, carry out mould preheating and surface coating treatment to ensure clear casting outline and intact marking on the elbow blank.
2.Investment Casting & Forming
3.Deburring, Shot Blasting & Machining
4.Surface Pretreatment
5.Composite Electro-galvanizing & Hot-dip Galvanizing
6.Final Inspection & Packaging
2.Investment Casting & Forming
Melt qualified A36 carbon steel under precise temperature control. Pour molten steel into the pre-treated mould cavity to form integrated 90° elbow blanks with socket holes and pre-cast threaded boss positions. Control pouring speed and cooling rate to avoid shrinkage, porosity and deformation, guarantee uniform wall thickness and complete contour of the elbow body.
3.Deburring, Shot Blasting & Machining
Remove casting sprues, flash and burrs by grinding and shot blasting to clear residual sand and oxide scale on inner and outer surfaces. Carry out precision machining on the threaded bosses, tap internal threads for hex socket set screws. Ensure the socket inner diameter meets the tolerance requirement for matching round pipes.
4.Surface Pretreatment
Conduct multi-step pretreatment including degreasing, pickling and surface activation. Thoroughly remove oil stains, rust and oxide layers on the casting surface. Clean and dry the workpiece to get an active, clean substrate, which improves the adhesion of subsequent composite zinc coating.
5.Composite Electro-galvanizing & Hot-dip Galvanizing
Adopt combined electro-galvanizing and hot-dip galvanizing process to form composite anti-corrosion zinc layer with total thickness up to 80μm. Electro-galvanizing provides a uniform base zinc layer, then hot-dip galvanizing builds up thick protective coating. This treatment greatly enhances rust resistance and corrosion resistance, suitable for outdoor and humid working conditions.
6.Final Inspection & Packaging
Conduct full quality inspection including coating thickness test, dimensional check, thread fit test and appearance inspection. Mark qualified products with grade and batch information. Pack finished galvanized elbows with protective packaging to prevent scratches and collision damage during storage and transportation.
