Stainless steel (low-carbon steel with ≥10% chromium by weight) is a versatile material for stainless steel sheet metal fabrication across industries (construction, automotive, aerospace, etc.). Its core properties (corrosion resistance, durability) make it a reliable choice for custom sheet metal parts that require long-term performance in harsh environments.

At Marigold Rapid, we mainly use below four subtypes of stainless steel materials for producing sheet metal parts, but other materials are also available upon request:

SUS 301
SUS 304
SUS 316

SUS 430

Steel offers ideal properties for industrial sheet metal fabrication: rigidity, longevity, heat resistance, and corrosion resistance. Steel sheet metal prototypes excel at complex designs and precision sheet metal components (requiring tight dimensional accuracy). It’s also cost-efficient for sheet metal production and supports high-quality surface finishes (e.g., polishing).

At Marigold  Rapid, we mainly use two subtypes of steel materials for sheet metal parts:

Cold Rolled Steel
Galvanized Steel

Sheet metal sandblasting is a core surface treatment for custom sheet metal parts and sheet metal prototypes—it cleans, deburrs components, and acts as a pre-treatment (for sheet metal anodizing or painting) to boost coating adhesion. The process uses controlled abrasive media spraying to create unique textures (frosting, pebbling) for sheet metal parts.

At Marigold Rapid, we also offer aquablasting and bead blasting for sheet metal surface finishing—delivering uniform results for sheet metal components at low cost and short lead times.

Sheet metal anodizing is a widely used process for aluminum sheet metal parts: it enhances corrosion resistance, boosts surface hardness, improves wear resistance, and aids heat dissipation for sheet metal components.

At Marigold Rapid, we primarily use Type II anodizing for sheet metal prototypes—enabling custom tinting/dyeing to elevate aesthetic appeal. Type III anodizing (available on request) is ideal for sheet metal surfaces that require extra hardness (e.g., high-wear sheet metal components).
 

Sheet metal painting is a versatile treatment for sheet metal prototypes and low-volume production sheet metal parts. It supports diverse finishes (matte, glossy, textured, soft-touch) and fully custom color options (per customer request).

Our sheet metal painting service serves industries including electronics (sheet metal enclosures), medical devices (sheet metal components), wearable device sheet metal prototypes, and automotive sheet metal parts—aligning with functional and aesthetic needs.

Sheet metal powder coating applies a dry plastic powder to metal sheet metal parts, then cures it (via heat) to bond with the surface—delivering a durable, long-lasting finish.

This process is ideal for sheet metal prototypes like household appliance sheet metal components, drum hardware sheet metal parts, and automotive/motorcycle/bicycle sheet metal prototypes.

At Marigold Rapid, popular colors include black, silver, white, blue, and red (custom colors available for sheet metal projects).
