When it comes to custom sculptures and art installations, the base plays a vital role in both structure and aesthetics.

A well-designed base not only provides stability and durability, but also enhances the visual harmony of the entire artwork.

we’ll explore two of the most common types of sculpture bases — stainless steel bases and marble bases — and explain their installation methods, advantages, and application scenarios.

一 . Stainless Steel Base Installation Methods

1.1 Features and Advantages

Stainless steel bases are widely used for modern or Outdoor Sculptures due to their durability and clean, contemporary look.

Key benefits include:

Excellent corrosion and moisture resistance

High load-bearing capacity

Customizable finishes: mirror polish, brushed, matte, or sandblasted

Ideal for minimalist, modern, or architectural artworks

1.2 Common Installation Methods

A. Internal Welding Installation

Application: Medium To Large Metal Sculptures

Method:

A steel plate or square tube is pre-installed inside the base；The sculpture’s mounting rod or embedded part is inserted into the structure；Welding and surface finishing are performed after alignment

Advantages: very strong connection and seamless appearance

 B. Bolt Connection (Detachable Type)

Application: sculptures that require transport or temporary display

Method:

Bolt holes are pre-drilled on the top plate of the base

The sculpture bottom is equipped with threaded inserts or flanges

Stainless steel bolts are used to secure both parts

Advantages: easy installation and convenient disassembly

C. Ground Anchoring Installation

Application: outdoor or large-scale public art projects

Method:

Stainless steel anchor bolts are embedded into the concrete foundation

The base bottom plate is fixed to the anchors with bolts

Seams are sealed with structural adhesive or waterproof silicone

Advantages: high wind resistance and long-term stability

二. Marble Base Installation Methods

2.1 Features and Applications

Marble bases are often chosen for indoor sculptures or memorial artworks due to their luxurious texture and timeless appearance.

Common materials: black granite, white marble, sesame gray, or customized stone options.

Advantages:

Natural stone beauty

Strong and heavy structure

Matches bronze, resin, and stainless steel sculptures

2.2 Common Installation Methods

A. Metal Insert Fixing

Method: stainless steel bolts or threaded rods are pre-embedded in the marble base

Connection: sculpture bottom is fixed by nuts or flanges

Advantages: solid, durable, and vibration-resistant

 B. Structural Adhesive + Position Pin

Method: apply industrial adhesive between base and sculpture, plus positioning pins for alignment

Suitable for: small to medium-sized artworks

Tip: ensure clean and level surfaces before bonding

C. Slot Embedding (Mortise-Tenon Structure)

Method: carve a slot or recess into the marble according to the sculpture’s base shape

Advantages: invisible joint, perfect visual unity

Recommended for: galleries, museums, or high-end private collections

3、Installation Tips and Precautions

Always keep the base level and stable using a spirit level

Confirm that the base’s load capacity exceeds the sculpture’s total weight

For outdoor installations, apply waterproof and anti-slip treatment

For safety, transport the base and sculpture separately and assemble on site

 Conclusion

Both stainless steel bases and marble pedestals offer unique advantages in sculpture presentation and structural support.

Choosing the right installation method ensures that your artwork remains safe, stable, and visually balanced for years to come.
