GB Reinforcement Plate (H-028) — GB/T 6170 / ISO 4032 (Series 065)

GB is the international standard for reinforcement plate (h-028) — gb/t 6170 / iso 4032 (series 065). This page sets out what the standard governs, the size range it specifies, and the related standards you will see referenced in datasheets.

GB — Scope

GB specifies the dimensions and tolerances of reinforcement plate (h-028) — gb/t 6170 / iso 4032 (series 065). Material, property class, surface finish and packaging are governed by separate documents in the same standards family (for example ISO 898-1 for the mechanical property classes of bolts and screws).

Tolerance & Product Grades

GB, alongside the related GB/T 6170 / ISO 4032 entries on this site, specifies product grades (typically A or B for fine work and C for general engineering) and tolerance classes for the controlling dimensions. Choose the grade against the precision your application requires.

Companion Standards

GB controls only the geometry of reinforcement plate (h-028) — gb/t 6170 / iso 4032 (series 065). The mechanical strength is set by ISO 898-1 (bolts and screws) or ISO 898-2 (nuts); the surface finish is governed by separate finish standards (e.g. ISO 4042 for electroplating). For corrosion testing, the relevant document is ISO 9227 (neutral salt spray).

When to Specify GB

Choose GB for international engineering work and OEM supply where ISO standards are the contractual reference. It is the default modern specification for reinforcement plate (h-028) — gb/t 6170 / iso 4032 (series 065).

Frequently Asked Questions

When did GB last revise its dimensional table?

ISO standards for reinforcement plate (h-028) — gb/t 6170 / iso 4032 (series 065) are reviewed on roughly a five-year cycle. Always reference the latest published edition (or the edition cited contractually); the dimensional table on this page reflects the current commercially-supplied form.

What does GB specify for Reinforcement Plate (H-028) — GB/T 6170 / ISO 4032 (Series 065)?

GB specifies the dimensions and tolerances of reinforcement plate (h-028) — gb/t 6170 / iso 4032 (series 065). Material and property class are governed by separate standards in the same family.

What product grades does GB define?

GB typically distinguishes product grades for precision (A/B) and general engineering (C). The selection for Reinforcement Plate (H-028) — GB/T 6170 / ISO 4032 (Series 065) depends on the precision your application requires.

Does GB specify the mechanical strength?

No. GB controls only the geometry of reinforcement plate (h-028) — gb/t 6170 / iso 4032 (series 065). The mechanical strength is set by ISO 898-1 (bolts / screws) or ISO 898-2 (nuts), and the finish is governed by separate standards.
