Description

A Compression Coil Spring is a mechanical spring designed to resist axial compressive forces by shortening in length when a load is applied. It stores mechanical energy and releases it when the load is removed, providing cushioning, shock absorption, and load-bearing support in a variety of applications.

Key Features:
  • Design: Helical coil shape that compresses under load and returns to its original length when unloaded

  • Material: Made from various spring materials such as high-carbon spring steel, stainless steel, or alloy steel, selected based on application requirements

  • Durability: High fatigue resistance to endure repeated compression cycles without permanent deformation

  • Versatility: Available in numerous sizes, wire diameters, coil diameters, lengths, and load capacities

  • Surface Treatment: Can be coated, plated, or shot-peened to enhance corrosion resistance and performance

 DescriptionWhat Is a Tension Spring?

A tension spring (also called an extension spring) is a helical spring designed to operate under tension — it stretches when force is applied and returns to its original shape when the force is removed.

When made from stainless steel, these springs offer excellent corrosion resistance, strength, and durability, making them ideal for harsh or outdoor environments.

Key Features:

 

PropertyDescription
Material Stainless Steel (commonly grades 302, 304, or 316)
Type Helical extension spring
Coil Direction Typically right-hand, but can be custom
Ends Hooks, loops, or custom eyelets for attachment
Finish Natural stainless (can be polished for aesthetics)
Corrosion Resistance Excellent – suitable for marine, food, medical, or outdoor applications

Description

A garter circular spring is a specialized spring formed into a continuous circular loop, designed to exert uniform radial tension. It is commonly used to provide consistent sealing pressure or maintain tension around cylindrical components. Constructed from high-strength spring wire, garter springs are valued for their reliability, flexibility, and ability to maintain force in dynamic applications.

⚙️ Key Features:
  • Shape: Circular loop, often with ends joined by hooks, welds, or clips to form a continuous ring.

  • Material: Typically made from high-carbon spring steel, stainless steel, or other alloy steels for strength and corrosion resistance.

  • Function: Provides uniform outward radial force, maintaining tension or seal around shafts, pipes, or seals.

  • Durability: Designed for repeated compression and expansion cycles without loss of tension.

Description

Tension helical springs, also known as extension springs, are coiled springs designed to absorb and store energy by resisting pulling (tensile) forces. These springs elongate under load and return to their original length when the load is released, providing a restoring force that keeps components securely connected.

Key Features:
  • Design: Helical coils with hooks, loops, or other end attachments for easy installation and load transfer.

  • Material: Typically made from high-strength carbon steel, stainless steel, or alloy steel for durability and fatigue resistance.

  • Function: Provides a pulling force by extending under tension and returning to original shape when unloaded.

  • Performance: Delivers consistent tension force, excellent fatigue life, and resistance to deformation.

  • Sizes: Available in various wire diameters, coil diameters, lengths, and load ratings.

 Description

A Taper Extension Spring is a specialized extension spring featuring a tapered design where the coil diameter or wire thickness gradually changes along its length. This tapering allows the spring to provide a varying load and controlled extension characteristics compared to standard extension springs.

Key Features:

 

  • Design: Helical extension spring with coils that taper from larger to smaller diameters (or vice versa), enabling progressive force distribution during extension

  • Material: Made from high-quality spring steel, stainless steel, or alloy materials for strength, flexibility, and corrosion resistance

  • Function: Provides controlled extension force with variable tension, reducing sudden shocks and ensuring smoother operation

  • Durability: High fatigue resistance suited for repeated stretching and loading cycles

  • Customization: Available in various lengths, wire diameters, and taper profiles to fit specific application needs

Description:What is an Extension Spring?

An extension spring is a type of helical spring designed to store energy and resist pulling forces. It operates with tension — the spring stretches when force is applied and returns to its original shape when the force is released.

When made of mild steel, the spring is cost-effective and suitable for low to moderate load applications.

Key Characteristics:

 

PropertyDescription
Material Mild Steel (Low-Carbon Steel)
Wire Shape Round (standard) or square
Coil Type Helical, tightly wound with initial tension
Ends/Loops Hooked ends (English, German, or custom loops) for attachment
Surface Finish Can be raw, painted, galvanized, or zinc-coated
Tensile Strength Moderate – less than stainless or high-carbon steels
Corrosion Resistance Low unless coated or used indoors

DescriptionWhat Are Trampoline Springs?

Trampoline springs** are tightly wound helical extension springs that connect the trampoline mat to the frame, enabling the bounce by storing and releasing elastic energy. When made from stainless steel, they offer superior durability, corrosion resistance, and longer lifespan — especially for outdoor use.

Key Characteristics:

 

PropertyDescription
Material Stainless Steel (commonly 302, 304, or 316 grades)
Spring Type Extension spring with closed coils and hooked ends
Hook Type Typically machine-loop or double loop hooks for secure attachment
Coating Often uncoated (raw stainless), since stainless is inherently corrosion resistant
Elasticity High – allows repeated stretching and recovery without deformation
Weather Resistance Excellent – resists rust, rain, UV, and sweat exposure
Finish Shiny metallic; sometimes polished

 Description:

Wire forming springs (or wire forms) are custom-shaped metal wire components designed to store force, maintain tension, or provide mechanical resistance — but unlike traditional coil springs, they’re not limited to helical or spiral shapes.

They can be bent, twisted, looped, or angled into nearly any configuration to perform a specific function in a mechanical system.

Key Characteristics:

 

FeatureDescription
Material Usually spring steel, stainless steel, mild steel, phosphor bronze, etc.
Shape Custom – includes hooks, angles, loops, zig-zags, clips, torsions
Function Apply force, hold components, return movement, absorb shock
