Forging provides greater strength and reduced weight Instead of using traditional casting technology that is typical of tripod construction, Sirui is a pioneer who adopted the forging technique in manufacturing. During the forging process, the deformation and cooling of metal causes the structure of the metal to be stronger and compact - greatly increasing its strength-to-weight ratio. This allows Sirui to build products with exceptional strength and durability, that are surprisingly light. The added strength of forging allows thinner, lighter components. Temperature Tolerance Test We torture-test all of our products - under conditions that far exceed what most people will ever experience (-40° ~ 100°C/-40° ~ 212°F). SIRUI is the first Chinese manufacturer to continuously perform the 4-hour test on all tripod, monopod and ball head models.
