Shipping and Delivery

Getting a product to market as quickly as possible is essential in today’s economy. Quite often, we can deliver your order by the time our competitors provide you with a price quote! We have structured our entire business for quality, speed and dependability. We are equipped with delivery vehicles that service the Silicon Valley and most of the San Francisco Bay Area. This drastically improves delivery times and cuts shipping costs, which in turn, is passed to our customers!

Our Machinery

Peninsula Spring has an array of specialty machines that are capable of laser cutting, punching, coiling, grinding, and bending spring materials to almost any size, shape and angle desired. From spring prototypes to production quantities, we are able to fabricate parts both quickly and cost effectively.

Peninsula Spring specializes in prototype and short-run orders. There is no job too small for us. However, we are also well equipped to handle large production orders. No matter the quantity, we provide the same service and quality for each order.
