Structural steel detailing services we offer are flexible and cost effective. We offer solutions in engineering drafting, ensuring a high level of quality and delivering on time at the same time. Trinity CAD Services offers excellent detailing, design, and structural drawings through CAD programs. We fulfill not only our clients’ requirements to perfection but also their desires.


Steel Detailing is the process of translating design /engineering /contract drawings to detailed shop drawings. We have Steel detailing professionals with many years of experience in structural steel detailing projects. We can produce complete detail drawing for structural steel, stair & rails, all types of miscellaneous items, industrial projects, and bridge projects.


Steel shop drawings that are made with the help of high-end technologies ensure that engineers and planners are able to easily appreciate the details that need to be taken into consideration when planning and setting up a structure. We offer structural steel detailing services (including miscellaneous items) for a broad range of applications to meet our clients' needs.


Erection Drawings:


Erection drawings are used to guide the steel erector on the construction site

as to where and how to erect the fabricated steel members. These drawings usually show dimensioned plans to locate the steel members, and they often also show details with specific information and requirements, including all work that must be done in the field (such as bolting, welding or installing wedge anchors).

Shop Drawings:


Shop drawings, also called detail drawings, are used to specify the exact detailing requirements for fabricating each individual member of a structure, and are used by the steel fabricator to fabricate these members. Complete shop drawings show material specifications, member sizes, all required dimensions, welding, bolting, surface preparation and painting requirements, and any other information required to describe each completed member.
