shims and foils

Manufacturer, Supplier & Exporter of Shims and Foils

Riddhi Siddhi Impex is a leading manufacturer and supplier of precision shims and foils, offering a diverse range of products including stainless steel shim stock, laminated (“peelable”) shims, foil, spacer shims, slotted shims, and custom configurations. Our materials include high-grade stainless steels (such as 301, 302, 304, 316, 321), carbon steel, aluminum, brass, copper, titanium, and specialty alloys. Manufactured to international standards (ASTM, ASME, DIN, JIS), our shims and foils are engineered for tight dimensional tolerances, thickness accuracy, and exceptional surface quality—perfect for high-precision, high-reliability applications

As a trusted Shims/Foils Domastic supplier, Riddhi Siddhi Impex serves industries in India’s major metro areas—Mumbai, Delhi, Bengaluru, Hyderabad, Chennai, Kolkata, Pune, Ahmedabad, Surat, Vadodara, and Rajkot. Whether customers need shim stock in rolls, pre-cut sheets, or laminated peelable shims in thicknesses as low as 0.02 mm, we ensure consistent quality, fast logistics, and superior service.

We also support industries in tier-2 and tier-3 cities across the country—Nagpur, Indore, Bhopal, Jaipur, Kanpur, Lucknow, Agra, Varanasi, Amritsar, Chandigarh, Mysuru, Udaipur, Jodhpur, Visakhapatnam, Coimbatore, Madurai, Kochi, Thiruvananthapuram, Mangalore, Nashik, Kolhapur, Chandrapur, Akola, Vilayat, Somnath, Dahej, Narmada, Navsari, Valsad, and Rajpipla. Our logistical network ensures reliable delivery of shim rolls, foil, and precision-cut shims for manufacturing, maintenance, and assembly use—wherever needed.

Riddhi Siddhi Impex specializes in customization: you can request laminated (peelable) shims, edge-bonded adjustable shims, slotted “horseshoe” shims, flat sheet, or spacer shims in custom thicknesses or dimensions to suit specific assembly and alignment needs. These flexible configurations are vital for precision fitting, leveling equipment, and adjusting clearances in sectors like petrochemicals, power generation, automotive, aerospace, and construction.

Quality control is rigorous—every batch of shims and foils comes with a Material Test Certificate (MTC) confirming chemical and mechanical compliance. We also offer cutting services like lasering, waterjet, and stamping for custom shapes and support tight tolerances and surface finishes per customer requirements.
