Lower cost alternative to stainless steel sheet metal. Ultimate service life depends on coating thickness and the severity of the environment. Prix concurrentiel : Nous pouvons offrir des prix concurrentiels à nos clients. G30, G40, G60 AND G90: UNDERSTANDING ZINC-BASED COATING WEIGHTS EXECUTIVE SUMMARY Zinc-coated, or hot-dipped galvanized, steel is a widely used material in numerous applications, thanks to its corrosion-resistance, strength and relatively inexpensive cost. The corrosion resistance of the “G” type is directly related to the amount of zinc coating, i.e., G90 will resist corrosion to the base metal longer than G30. 0000009998 00000 n For certain applications, it offers a substantial increase in corrosion resistance over G90 galvanized sheet. 0000004993 00000 n HOT DIP GALVANIZED STEEL, known as ZINCGRIP® Steel, is continuously coated on both sides with a zinc coating. The hot dip process, pioneered by AK Steel, provides a tight metallurgical bond between the steel and the coating. Hence, the service life of a G90 will generally be 3 times that of a G30 and 1.5 times that of a G60 in the same environment. SI VOUS AVEZ N'IMPORTE QUELLES QUESTIONS, VEUILLEZ NE PAS HÉSITER À ME CONTACTER ! Freshly exposed galvanized steel reacts with the surrounding atmosphere to form a series of zinc corrosion products. When comparing the amount of zinc, the galvanized G90 has more than the galvanneal steel A40. Galvanized steel consists of a thin coating of zinc fused to a steel substrate. This process results in a material with the strength and formability of steel plus the corrosion protection of zinc. Manufactured to high-quality standards to ensure solid performance, this U-shaped rigid tie features a G90 galvanized finish for added corrosion resistance and requires the use of hot-dip galvanized fasteners. typical G90 coating. �S�$�$}�2[�`��~V������.�_�b}R��RIH�|������B��~�IF����Q��V�h!h�:�It�{sf�R#L4ٰ-�D�Y��R*�)5�4���SUΟE��A�鯚��gL�2B$}8c���D�\}Z����%��'�1�J21jR%��Ik5Fht������]KDK$|��Y穇F���v�R�:U��w���3}�˵�������E��S�o�^�}^�_�Ŧ_?�p�C�S�����@s�=��b��o�1�����:S=�*t�%X����Ζ�O(��rM�3��_�/�в�-�FgZ�fȈ3�`�$��=|�n�F+��fڊh�j�5}��@+Q���.����e�բ-3g��h��q��u�Ј�U*��*x �,���mme=�k��L�>�rq-V�큺����������+��~:ZR�~ ����@���9�` ć � endstream endobj 31 0 obj 691 endobj 32 0 obj << /Filter /FlateDecode /Length 31 0 R >> stream G60 – .60 oz coating per square foot. 18 0 obj << /Linearized 1 /O 20 /H [ 1420 335 ] /L 217679 /E 201579 /N 4 /T 217201 >> endobj xref 18 49 0000000016 00000 n Galvanized Minimized Spangle Steel. In air, newly exposed zinc reacts with oxygen to form a very thin, tenacious zinc oxide layer. For zinc-rich 0000004366 00000 n For zinc-rich When the steel is withdrawn from the galvanizing bath, the zinc has a clean, bright, shiny surface.
