What Technical Parameters to Specify When Signing a GRC Supply Contract? Qinglong GRC Contract Technical Terms Guide

The technical clauses of a GRC supply contract are the cornerstone of project quality assurance and require clear, specific technical parameters and acceptance criteria. Based on 28 years of contract management experience, Qinglong GRC has developed a complete technical clause system.

In the Shanghai Century Plaza project, the technical annex of the contract ran to 32 pages, detailing 186 technical parameters, including: mechanical properties (flexural strength ≥18MPa, elastic modulus ≥15GPa); durability indicators (frost resistance F200, impermeability P10); appearance requirements (color difference ΔE≤2, flatness 2mm/2m); and tolerance standards (dimensional deviation ±1.5mm). These detailed technical specifications provided a clear basis for project acceptance and effectively prevented later disputes.

Material Performance Parameters

Mechanical properties: compressive strength, flexural strength, elastic modulus, etc. Physical properties: density, water absorption, thermal parameters, etc. Durability: frost resistance, impermeability, carbonation resistance, etc. These parameters require clearly specified testing standards and acceptance values.

Appearance Quality Requirements

Color uniformity: color difference range. Surface quality: flatness, smoothness. Dimensional tolerances: allowable deviations in length, width, and thickness. Joint requirements: width, straightness.

Acceptance Criteria and Methods

Sampling ratio: sample quantity per batch. Testing methods: standard numbers and versions. Acceptance rules: acceptable quality level. Dispute handling: re-inspection procedures and time limits.

Packaging and Transportation Requirements

Packaging method: protection level. Transportation requirements: handling and stacking regulations. Marking content: complete product information. Acceptance procedure: delivery inspection items.

Contract technical clauses need to be specific and actionable. It is advisable to engage professional technical personnel to review the contract and ensure the clauses are complete and accurate. Qinglong GRC provides standard technical annex templates that can be adjusted and refined according to project requirements.
