If you source cookware accessories for brands, retail distributors or private-label projects, you may have struggled to find a stable supplier for rectangular lids that fit fish pans, griddles and rectangular stockpots. As a professional G-type glass lid manufacturer, we produce tempered rectangular glass lids tailored for non-round cookware, supporting OEM customization and bulk wholesale.
This sourcing guide breaks down product specifications, material options, customization rules, supplier selection standards and order terms. It helps you evaluate suppliers and make confident purchasing decisions for your cookware line.
A G-type tempered glass lid is a rectangular cookware cover with rounded corners, specially engineered for rectangular pots, griddles, and fish pans. Unlike standard round glass lids that only fit circular cookware, this rectangular G-type design delivers a snug, stable seal for elongated pans.
Its core structure includes a clear tempered float glass panel, a polished stainless steel rim, a pre-drilled center hole for fitting a heat-resistant knob (knob not included), and a small side steam vent. The vent releases excess internal pressure to stop liquid from boiling over during cooking. The transparent glass lets cooks view food progress without lifting the lid and losing heat.

All our G-type glass lids are built with two core components: float glass and stainless steel rim, with multiple grades and thicknesses available for different budget and food safety requirements.
Both options feature high clarity for easy cooking monitoring.
The metal rim reinforces the glass edge to prevent chipping while creating a tight fit with cookware. Three stainless steel grades are available:
| Grade | Features | Food Contact Suitability | Best For |
|---|---|---|---|
| SUS 201 | Budget-friendly, basic rust resistance | General domestic use | Domestic low-to-mid tier cookware |
| SUS 202 | Balanced performance and price | General export compliant | General export wholesale orders |
| SUS 304 | Superior anti-corrosion performance | Food-safe for global markets | Premium cookware, EU/US food-contact markets |

Standard production sizes cover 16 cm to 30 cm. We also support fully custom dimensions to match your unique rectangular cookware moulds.
As a reliable cookware glass lid OEM supplier, we support flexible customisation to match your private label requirements.
