Objectives

The primary objective of this tender is to establish a qualified supply agreement for the procurement of precision metal raw materials required for manufacturing sealing strips and caulking wires. The procuring entity aims to secure competitive, transparent pricing and reliable delivery of standardized alloy products to support continuous operational and production requirements.

Scope of Supply

The tender covers the supply of two distinct product categories across four specified alloy types:

• Sealing Strip Material: Flat metal strips priced and supplied by weight (per kilogram).
• Caulking Wire Material: Metal wires priced and supplied by length (per metre).

All materials must be available in the following grades:

• X6CrMo17m
• X39CrMo17m
• X20CrMo13KG
• Bronze

Technical Requirements

Bidders must demonstrate the ability to supply materials that strictly comply with the following specifications:

• Dimensional Tolerances: Sealing strips must be manufactured to precise thickness and width combinations, specifically 0.30mm, 0.50mm, and 2.00mm thicknesses, with widths ranging from 10mm to 20mm. Caulking wires must conform to exact cross-sectional profiles, including rectangular sizes (e.g., 1×1.7mm, 2×3.0mm) and circular diameters (e.g., 2mm).
• Pricing Format: Quotations must be submitted exclusively in South African Rands, excluding VAT. Separate unit rates are required for strips (per kg) and wires (per m).
• Quality Assurance: Suppliers must guarantee that all delivered materials meet standard industrial specifications for the listed alloys, including consistent mechanical properties, surface finish, and dimensional accuracy. Provision of mill test certificates or material compliance documentation is expected.

Terminology Explanation: The alloy codes (X6CrMo17m, X39CrMo17m, X20CrMo13KG) denote European EN-standard martensitic stainless steels, selected for their high corrosion resistance, hardness, and suitability for dynamic sealing environments. "Caulking wire" refers to a compressible metal wire used to fill and seal narrow gaps between mating components, requiring uniform ductility and tensile strength to maintain effective seals under pressure.

Skills and Experience Requirements

Although the tender documentation does not explicitly mandate formal certifications, successful bidders will inherently need to demonstrate:

• Proven track record in sourcing, processing, or distributing precision metal raw materials, particularly stainless steel and bronze.
• Technical competency in metallurgical standards, quality control procedures, and tolerance verification for sheet and wire products.
• Operational capability to manage inventory, maintain consistent supply chains, and fulfill orders with minimal lead times.
• Financial and logistical capacity to handle volume procurement, ensure timely delivery, and comply with standard commercial payment terms.
