The highway bridge plate rubber bearings strictly implement the provisions of JT/T4 - 2019 "Highway Bridge Plate Rubber Bearings" and JT/T663-2006 "Specification Series of Highway Bridge Plate Rubber Bearings." This product further optimizes its design parameters and structural types after summarizing the experience of various designs, manufacturing, and applications of plate rubber bearings in the past, and the comprehensive performance of the product has been further improved.

The GPZ (KZ) series seismic-resistant pot bearings strictly adhere to the JT/T 391-2019 "Pot Bearings for Highway Bridges" standard and are designed in accordance with the provisions of the European standard EN 1337.

The GPZ (II) type bowl-shaped rubber bearing consists of an upper seat plate, a lower seat plate, a middle steel plate, a pressure-bearing rubber plate, a copper sealing ring, a rubber sealing ring, a polytetrafluoroethylene plate, an SF-1B composite plate, and a stainless steel plate. The bearings are divided into 31 specifications based on vertical load capacity ranging from 0.8MN to 60MN, with the horizontal load capacity of unidirectional movable bearings and fixed bearings being 10% of the vertical load capacity.

The GPZ (II) series pot bearings are designed according to the Ministry of Transport industry standard JT 391-2019 "Pot Bearings for Highway Bridges". This product is based on over twenty years of research and production application of highway pot bearings, referencing the standards and technologies of European and American pot bearings, and optimizing the GPZ series pot bearings.

JT/T391-2019 "Highway Bridge Pot Bearings", GPZ (2019) series pot bearings are the supporting drawings for this standard.

The GPZ (2019) type highway bridge pot rubber bearing consists of an upper plate, lower plate, intermediate steel plate, pressure-bearing rubber plate, copper sealing ring, rubber sealing ring, polytetrafluoroethylene plate, SF-1B composite plate, stainless steel plate, dust ring, and others. The bearings are divided into 33 specifications based on vertical load capacity, ranging from 0.4MN to 60MN. Its structure is consistent with that of ordinary pot rubber bearings, with the addition of a dust ring to prevent contamination of the lower plate's pot cavity in harsh environments. The horizontal load capacity of the unidirectional movable bearing and fixed bearing is 10% of the vertical load capacity.

The Lasso seismic isolation pot rubber bearing consists of an upper plate, a lower plate, an intermediate steel plate, a pressure-bearing rubber plate, a copper sealing ring, a rubber sealing ring, a polytetrafluoroethylene plate, an SF-1B composite plate, a stainless steel plate, and high-strength steel cables, among others. Its structural feature is the use of high-strength steel cables (steel strands, high-strength wire bundles) to restrict the upper and lower plates within the effective displacement range of the bearing.

The QZ series spherical bearings strictly adhere to the national standard GB/T 17955-2019 "Bridge Spherical Bearings", while also referencing the European standard "Structural Bearings" Part 7 "Spherical and Cylindrical PTFE Bearings" (EN 1337-7) and Part 2 "Sliding Elements" (EN 1337-2), as well as the British standard BS 5400 "Steel Bridges, Concrete Bridges and Composite Bridges" Part 9 "Bridge Bearings". They feature flexible rotation and large angles, making them particularly suitable for wide bridges, curved bridges, ramp bridges, skew bridges, and large-span bridges.
