Rectangular Studs

Rectangular Weld Stud

Found in just about every process that utilizes heat, refractories are a vital component of industrial manufacturing. However, improper securement can cause unwanted downtime, equipment failure, and accidents.

Improve the security of refractory and fireproofing materials with rectangular studs from Delta Stud Weld. As a leading provider of fastening solutions, we specialize in the quick turnaround of custom rectangular studs manufactured from domestically supplied materials.

Types of Rectangular Weld Stud

Benefits of Rectangular Studs

Rectangular weld studs are specially fabricated studs used to secure refractory castables, board, ram plastics, wire mesh, and fireproofing materials to the inside or outside of furnace shells. Commonly called rectangular arc weld studs, they also aid structural beams in the case of fireproofing. 

Unlike cylindrical studs, these rectangular fasteners can be outfitted with grooves, notches, or holes that support refractory and insulation linings. Industries that utilize rectangular studs include: 

  • Oil and gas
  • Forging and heat treatment 
  • Aluminum and non-ferrous metals
  • Marine 
  • Signage and construction
  • Hardware

Types of Rectangular Studs

Delta Stud Weld is your source for high-quality rectangular studs. Our area of expertise is the rapid design, manufacture, and delivery of heat-resistant rectangular weld studs for demanding high-temperature applications. Here are our capabilities: 

  • Two tine
  • T-slotted 
  • Rectangular stud with a hole

Rectangular Studs Material Types

Rectangular studs need to be fabricated from high-quality materials because, being closest to the hot face, they experience the highest temperatures. Delta Stud Weld manufactures all high-temperature refractory hardware using metal alloys sourced from trustworthy domestic mills. Common materials from which rectangular weld studs are made include: 

  • Low-carbon steel
  • 304 stainless steel 
  • 310 stainless steel 
  • 330 stainless steel 

When it comes to high-temperature environments, standard refractory hardware isn’t always suitable. That’s why Delta Stud Weld offers fast turnaround build-to-print and custom rectangular weld stud solutions.

Whether it’s a proven drawing or not-yet-conceptualized idea, we can take your plan from design to finished product. Our team is comprised of experienced engineering professionals, talented welders, and keen-eyed inspectors.

Inspectors use precision gauges to verify conformance with applicable industry standards or customer requirements. All raw material is checked for accuracy, and Material Test Reports can be supplied with shipments upon request. Orders are audited before load out.
