Frequently Asked Questions

What is the difference between quartz and borosilicate glass?

Quartz glass (fused silica) has higher temperature resistance (up to 1200°C) and better UV transmission. Borosilicate glass (e.g., Pyrex) offers excellent thermal shock resistance up to 500°C and is more cost-effective for many industrial applications.

Can you customize glass dimensions and shapes?

Yes. We offer full customization including CNC cutting, drilling, edge polishing, bending, and screen printing. Send us your drawings or specifications for a quote.

What flange standards do you support?

We manufacture flange sight glasses to DIN, ANSI, JIS, and custom sanitary (tri-clamp) standards using SS304 or SS316L stainless steel.

What is the lead time for custom orders?

Standard products ship in 7–10 days. Custom orders typically take 15–25 days depending on complexity and quantity.

Do you provide technical drawings and certifications?

Yes. We provide dimensioned drawings, material certifications, and test reports upon request.
