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 Fastener U Bolt Introduction
U Bolt is a special U-shaped tubular clamping fastener designed for pipe fixing, equipment positioning and structural
anti-displacement connection. Consisting of a bent U-shaped body and matched threads and nuts, it features simple structure,convenient installation and strong clamping stability. Manufactured from high-quality carbon steel and stainless steel materials conforming to DIN, ISO and ASTM standards, U bolts provide excellent tensile strength, bending resistance and structural durability under long-term load and vibration conditions. The arc inner surface perfectly fits circular pipe bodies, effectively preventing pipeline sliding, shaking and falling off. Widely applied in pipeline engineering, mechanical equipment fixing,automobile chassis suspension, container structural fastening, building steel structure support, marine piping and facility installation, U bolts are essential standard fasteners for stable clamping and positioning of tubular and circular structural parts.

A36 Fastener U Bolt Product Processing
1.Raw Material Inspection & Blanking:
Adopt high-quality carbon steel and stainless steel round bars that comply with DIN, ISO and ASTM industrial standards. Strictly inspect chemical composition, mechanical properties, surface smoothness and internal metallographic structure to eliminate cracks, oxide scales and inclusions. Qualified raw materials are precisely cut into fixed-length rod blanks according to U-bolt specifications, ensuring uniform length and consistent material performance for subsequent bending and threading processing.
2.Surface Pretreatment & Precision Bending Forming:
2.Surface Pretreatment & Precision Bending Forming:
Complete professional surface pretreatment including degreasing, pickling and phosphating to remove surface oil stains and oxide layers, improving processing accuracy and surface quality. Adopt die integral bending technology to form standard U-shaped arc structure. Strictly control bending radian, symmetry and opening size to ensure perfect fitting with circular pipe surfaces, realizing uniform stress distribution and stable clamping performance.
3.End Trimming & Thread Machining:
3.End Trimming & Thread Machining:
Perform precision cutting and trimming on both ends of the bent U-shaped rod to ensure flat end faces and consistent length. Adopt high-precision thread rolling and tapping technology to process standard threads at both ends. Strictly control thread pitch, tooth profile and tolerance grade to guarantee smooth nut assembly, accurate meshing and reliable locking effect.
4.Heat Treatment & Stress Relief:
4.Heat Treatment & Stress Relief:
Conduct standardized heat treatment including quenching and tempering for high-strength U-bolts and stress relief annealing for conventional and stainless steel models. The process effectively eliminates internal residual stress generated during bending and threading, stabilizes overall structural hardness and toughness, and improves bending resistance, tensile performance and long-term vibration fatigue resistance.
5.Surface Treatment & Quality Testing:
5.Surface Treatment & Quality Testing:
Implement customized surface treatments such as electro-galvanizing, hot-dip galvanizing, blackening and passivation to enhance anti-rust, anti-corrosion and wear-resistant capabilities. Carry out full-range professional inspections including dimensional tolerance detection, arc symmetry test, thread precision calibration, tensile strength test and bending resistance test to ensure all technical indicators meet industrial fastening standards and actual engineering application requirements.
6.Marking, Packaging & Warehousing:
6.Marking, Packaging & Warehousing:
Mark qualified U-bolts with strength grade, product specification, execution standard and production batch. Complete automatic sorting, counting and dust-proof, moisture-proof and collision-proof standardized packaging. All finished products are classified and stored in warehouses and delivered after strict final inspection.
