Structural services

Four services. One engineering team.

From the first load calculation to the last shop drawing, every structure is designed to code, checked twice and documented so contractors can build it without guesswork.

Structural Design & Analysis

Load calculation, modelling and member design for steel, RCC and composite structures.

Structural Detailing 2D / 3D

GA, fabrication, erection and reinforcement drawings, plus coordinated 3D models.

Industrial Structures

Pre-engineered sheds, factories, warehouses, mezzanines, crane gantries and pipe racks.

Residential & Commercial

Homes, apartments, villas, offices, showrooms and mixed-use buildings.

S1 — STRUCTURAL DESIGN & ANALYSIS

Safe, economical, code-compliant.

SteelRCC & composite

IScode-based design

We model the full structure, apply every load it will face and size each member so it is strong enough — and not a kilo heavier than it needs to be. Optimised design means lower steel and concrete quantities and a lower project cost.

From enquiry to completed project

How engineering and marketing work together.

Because one team runs both sides, nothing gets lost between the ad, the drawing and the site.

Enquiry

A factory owner searches for a PEB shed or sees a Meta ad — the lead lands in Metro CRM within seconds and is assigned to sales.

Scheme & quote

Our engineers propose the structural scheme and steel tonnage, so the quotation sent from the CRM is accurate from day one.

Design & drawings

Once confirmed, we complete the design, analysis and 2D/3D detailing for the fabrication shop and the site team.

Build & support

We answer site queries, revise drawings and issue as-built drawings when the structure is complete.

Showcase

Finished projects become website case studies, reels and ads — which bring in the next enquiry.

Why DigitalNgage for structures

Engineering you can build on.

Safety first

Every structure is designed to the relevant IS codes for wind and earthquake loads, and checked before any drawing is issued.

Economical design

Optimised member sizes and value engineering reduce steel and concrete quantities — and the project cost.

Build-ready drawings

Clear 2D drawings and 3D models with schedules and quantities mean fewer site queries and no rework.

Industrial know-how

Hands-on experience with PEB sheds, warehouses and PUF panel roofing through Metro Puf and Delta Infrastructures.

On-time delivery

Fixed milestones for concept, design and drawings, with quick revisions when the site needs them.

Engineering + growth

One partner for the structure, the website, the ads and the CRM — the only agency that can design your building and fill it with customers.

FAQ

Structural questions, answered.

What do you need to start a structural design?

The architectural drawings (plans, sections, elevations), the soil investigation report if available, the site location and how the building will be used. For industrial projects, also share crane, equipment and roofing requirements.

Do you design both steel and RCC structures?

Yes — steel, RCC, composite and pre-engineered (PEB) structures, including PUF panel roofing and cladding systems for sheds, warehouses and cold storage.

Do you provide only drawings, or design too?

Both. You can hire us for complete design and analysis with drawings, or only for 2D/3D detailing based on an existing design.

Which codes do you follow?

Indian Standards — including IS 456 (RCC), IS 800 (steel), IS 875 (loads), IS 1893 (earthquake) and IS 13920 (ductile detailing). Other international codes can be used when a project requires them.

Can you also market our construction or infrastructure business?

Yes. That's exactly what we do for Delta Infrastructures — structural engineering plus website, Meta Ads, SEO, social media and a sales CRM, all from one team.
