Designed for the sourcing work.
The extension opens in Chrome’s side panel, leaving the supplier or material page in view. The calculator and notebook work without a MetalSite account or internet connection. Website actions such as publishing an RFQ use the normal MetalSite sign-in and moderation process.
Continue the conversation.
Open Workspace in the extension to connect your account. Match the approval code on the website, then return to Chrome and check the connection. See your own account details and activity counts, refresh private conversations and send a reviewed reply. Manage or revoke connections from connected tools. Connections expire after two hours.
Your calculations and notes stay with you.
Saved notebook records are encrypted in the extension’s local Chrome storage. Remembering calculator inputs is optional. The extension does not monitor browsing history, read pages in the background, upload your notebook or place bids automatically. Selected text and its source URL are saved only when you use the capture action; URL query strings and fragments are removed.
Market data is optional. Access is requested only for metalsite.com, and can be removed inside the extension. Loading indications requests the chosen market and currency; normal connection metadata is also received by MetalSite and its hosting/CDN services.
A useful estimate, with clear limits.
Weights use nominal densities and simple straight-section geometry. Grade, tolerances, coatings and corner radii affect actual weight. Cost estimates use the unit price you enter and exclude freight, taxes, processing and wastage. Confirm the final details with your supplier.
Country market indications follow MetalSite’s published method. A number appears only when enough comparable reports pass review. These are reference indications, not executable offers or guaranteed exchange prices.
